### Thanks

You are so nice, thank you!

### abaqus tutorial 1

Cool, this kind of study material if shared ii good, I want to learn and improve my basics in non linear analysis, have any suggestion for me.

I want to learn the approach strategy for a fea problem, specially how the load is applied and boundary conditions, under which category this problem comes ect... please advise

### tutorial

Hello everyone,

When you create the model (for example a rectangle sample) in abaqus, I don't understand how you apply a crack and how you have a stress distribution in all the sample. Can somebody advise me ?

Infinity.

### I'm a student in the States

I'm a student in the States and I am needing an update tutorial site for abaqus.  I've read throught this site, but a few of the sites I've looked at are 3 and 4 year old tutorials.  I'm looking for help with engineering solids, for car and motorcycle parts .  Any suggestions for a good tutorial would be helpful.  Thanks

### textbook FEA of Composite Materials Using Abaqus

Although emphasis is in orthotropic and laminated materials, you can use most of the book, including many examples, to learn Abaqus/CAE. Many users have said it helped learn Abaqus even though they were not that interested in Composites but somethig else. Model generation, elements to be use, an so on are common for all applications of Abaqus. Ch. 2 Intro to FEA. Ch. 3 Elasticity. Ch. 4 Buckling. Ch. 5 deals with 3D stress, Ch. 6. also 3D, Ch. 7. viscoelasticity, Chapters 8 and 9. damage, and Ch. 10. delaminations. There are many solved examples with pseudo-code that you can follow to do the examples in Abaqus/CAE.

### abaqus training

I doubt the kind of learning that you need can be provided via comments here, and that you will get anything complete to your specific needs. It is better to apply to some training, either online or offline. A simple search results for abaqus training point to Simulia Services website. Here is a list of all available courses from them:

Hope this helps a bit... :)

### ABAQUS Documentation

ABAQUS documentation is a powerful and completed user's resource and easy to follow for beginners.

### ABAQUS modeling help.

### Abaqus

Noel,
Abaqus is a comercial package and its cost depends on where you intend to use e.g., Industry, University, Research centre etc. As far as I know, there is no way to legally get a trial version of this software for free. In any case you should consult Abaqus directly.

V. Hegadekatte, University of Karlsruhe, Germany

### Student Version

There is a student version though which has some size limitations (less than 1000 nodes). You need a student card to request one.

### need urgent help

dear all

I need help in my work i started to work with ABACUS and i suppose to work with shoulder data to review the reverse implant inside this shoulder.

i can not explain this very well but i need some expert in ABACUS to ask them what to do exactly or at least get me started.

Pleaseeeeeeeee i need an URGENT help......FROM ANY ONE.

Thank you

### Hyperelastic plate with circular hole

Hi Dear All,

I am Jamal, a PhD candidate from Cardiff University.

I try to model and validate an example of a hyperelastic plate with a circular hole problem.

The problem was demonstrated in a paper entitled 'FE formulation of the Ogden material model

with application to rubber like shells' by Y Basar and M. Itskov. Inter. Journal for Numerical

Methods in Engineering, 42, 1279-1305(1998).

I have modelled it in Abaqus 6.6.1 but the results seem not according to that journal paper.

Moreover, it's very difficult to get the results converged.

I have the journal paper and my abaqus results but I just don't know how to attach them here.

If anyone is interested to help me with this matter, I will e-mail the attachments.

### Re: Hyperelastic plate with circular hole

You cannot attach a file to a comment.  However, you can start a new post, and attatch a file with the post.  You can then add a comment here and make a link to your post.

### Re: Hyperelastic plate with circular hole

Dear Sir,

Thank you for your reply. However, I attempted to start a new post several times but failed to attach the files:

Remarks: "File attachment is disabled...."

### Problem with file attachment has been fixed

Thank you for letting us know of the problem with attachment.  This problem has been fixed now.  You can attach a file with a post.

### Blog entry posted

Dear All,

I have posted a blog entry entitled "Modelling Hyper-elastic Plate Using Abaqus" @ J Mahmud's blog. It describes my work on hyperlatic plate.

Thank you to everyone who has shown interest in my work.

### Help

Dear Sir

Is it possible to solve crack propagation problem with ABAQUS CAE? (i. e. with Graphical user interface)

### results fil

satish

iam not getting *fil file after running analysis in abaqus cae ,due to this iam not able to do pre&post process in hypermesh,can u guide me on this regard

### CAE doesn't create *.fil file

Satish,

When you create any model in CAE, it does not create *.fil by default. If you want *.fil file after analysis, you need to enter (*NODE FILE) or (*ELEMENT FILE) line manually in your input file. You need to enter the node set or element set(whatever u want) in that line and data line will include the variables, you want to write in the *.fil file.

You can look at *Node File section in ABAQUS keywords manual if you need more details.

Good luck!!!

### ABAQUS USER-MATERIAL...?

I want to define an special Behavior (Super-elastic ) for ABAQUS,and I tried to Link my UserMAterial routinr (UMAT) to the program but it doesn't identify my Fortran I don't know why? How can I do that

by the way is there anyone who had done kind of this job?

### You should check the .log

You should check the .log file for additional information on linking errors.

Also, there is a specialized ABAQUS users' forum on www.eng-tips.com where you can get some extra help.

Best,

Dan

### Compiler??

Have you checked if the right compiler and options are being used in
the environment file? Also, try to run your model with some standard
UMAT/VUMAT (as be the case) provided by abaqus. This might help you
narrow down the problem.

Arun

### Did you config your environment correctly?

did you install fortran compiler  and config the lib path and include path correctly? did you pass all the verification of abaqus?

### Abaqus Help Forums

This is in no means meant to replace any discusion here, but I thought these links might help. They are ABAQUS forums where you can get questions answered.

The official site (ABAQUS answers, requires registration)

The most popular (as far as I know) forum for Abaqus users (unofficial):

Hope this helps, please share any other resources you may know of.

Thanks.

### ABAQUS Yahoo group

Hi,

There is also a yahoo group, might find it helpful.

Although, I think this is somehow related to the abaqus users group in www.nabble.com

### ABAQUS 6.5 calculations

I have a question , Could I submit a calcul with tow user subroutine one DLOAD and one UMAT  in the same time ? and how can i do that ?

Thank's

### Re:ABAQUS 6.5 calculations

Yes, you can. You should place both (all) user subroutines in the same subroutine file which you further need to supply when running the job.

Thank you for the documents you have linked. I have a student version of abaqus and i effectively needed this type of document to understand a certain number of things. There are still options that are not obvious for me, but i think i am in the good way.

I was wondering if you had a tutorial concerning crack introduction in a 3-D sample. I would like to have a force representation in function of the mesh size. I don't know how hard a such representation is.

Once again, thank you for your help.

Best regards.

### Abaqus Software

Hello ay body in this forum can send me the software about abaqus even the trial version or low version only . I want to study this software but I don't have  any copy of the softeware..Please  help..

### Abaqus tutorial on

Dear Sir, I would like appreciate to provide me by a various types of abaqus  tutorials that are related to dynamic simulation. My research field is in the erosive wear of matewrials. Thanks in davance .

### Wear Simulation

Mr. Al-Bukhaiti,
Consult the abaqus documentation for a variety of tutorial problems. If you are working on a unix/linux system, then type "abaqus doc" on the command prompt to go to the documentation. Alternatively you can search on Google for "abaqus documentation" for a lot of links. I found the following link:

If you are interested in simulating wear using Abaqus, then you can refer to my papers/PhD thesis (http://vishwanath.hegadekatte.googlepages.com/curriculumvitae) which deals with wear of ceramic micro components. Also you will find there a review of the literature in this field. Most of my work is concerned with sliding wear, but may be useful for you.

### friction coefficient and slip rate

i try to solve stick-slip problem by abaqus 6.5-1,  when i enter to interaction property manager and choose the penalty and toggole on slip rate, the table appear, but the my problem is that, abaqus didnt accept negative value under slip rate becuase just i press on ok that message apear for me (allowable slip rate must be greater than or equal to zero)

so the question is who can i enter negative value to slip rate (relativ velocity)table?

HI

I work about Modelling and digital simulation of the structures fissured under residual stresses, I have the problem to calculate the J-integral when I have  in initial condition residuel stress, because Abaqus (6.5) define that

Initial stresses are not considered in the definition of contour integrals. Therefore, contour integral calculations for analyses including initial stresses in the regions used for the contour integral calculations will not be correct

I have many others problems see: Modelling and digital simulation of the structures fissured under residual stresses

### Structural effects due to thermal influences (e.g. laser, FSW)

Hello to everyone

I am doing my PhD at the Technical University of Munich (Germany)
and I want to simulate the structural effects of work pieces due to the thermal influence
of manufacturing processes like laser-beam-welding, laser-beam-cutting or
friction-stir-welding. Unfortunately I am more or less a beginner in ABAQUS,
but perhaps you can give me an advice how to start (a special tutorial for
thermal problems) or if it’s possible to simulate these kind of problems at all.

I would be deeply grateful for any help and

Mirko

Hi Mirko,

I think FSW is quite different from laser beam welding. Although both of them are joining process, the mechanism of FSW is far away from the traditional arc welding. So before your start, please decide which branch you should choose because both are not so easy to study. For FE simulation, I only carried out FEM calculation of arc welding, such as TIG, MIG and Laser. I highly recommend you to read Goldak's first paper of double eclipsoid welding pool model:COMPUTER MODELING OF HEAT-FLOW IN WELDS, METALLURGICAL TRANSACTIONS B-PROCESS METALLURGY 17 : 587 1986. That paper is a classical work.Another review is also good: Modeling of fundamental phenomena in welds,T Zacharia / J M Vitek / J A Goldak / T A DebRoy / M Rappaz / H K D H Bhadeshia,Modelling and Simulation in Materials Science and Engineering,3 (2), p.265-288, Mar 1995.

I dont know if the newest version of ABAQUS  provides the Goldak model or not. But another FE software MSC.MARC has already succeeded in implementation of Goldak model as GUI module. Anyway you can implement the model easily using subroutines.

FSW is still very difficult to model, because the FSW is not simply melt and solidification process. Dynamic recrystallization taks place dramatically in FSW. I think the FE simulation of FSW is much more difficult than arc welding.

I'm not sure what kind of problem you are interested in, but from what you described, I think your work may be related to residual stress/strain after welding or joining process. I think it is very challenging problem because of the highly nonlinear material properties and coupled phenomena. Good luck.

Best regards.

Wang

Hi, everyone! tanks for your attention! I am using ABAQUS for module FSI, during analysis, I get the error information:

The ratio of deformation speed to wave speed exceeds 1.0000 in at least one element. This usually indicates an error with the
model definition. Additional diagnostic information may be found in
the message file.

Who knows the reason for that? and can be remedy? Thanks.

### Difference in FEA result and EXP result

hi,

I am sajib.donig my unedrgrad thesis "strenghtening beam in flexure in two point load" using ABAQUS 6.4.

I got results but the beam analysis shows more stiff behaviour...a lot more than exp results.

i used correct E value. for beam 200X300X3000mm i used mesh size 25X25X25 mm,used t3d2 as steel and shell elements as FRP layer.i modelled 1/4 th of the beam and took advantage of symmetry.i also used rigid element to to apply load in two rows.and supported the beam by restraing 3 line of nodes along width in DOF 2.

can any one suggest me where may be the problem?

### drawing in yz plane

Hi

I am trying to make a shell model of a rectangular plate and need the part in the yz plane (I will eventually use the mesh coordinates, which need to be in the yz plane for another program). However I can't seem to draw in this plane, i can only do it in the xy plane which is the default? (The part has to be a 3D shell). Can anyone help? Thank you.

### What is the ideal data for tensile behaviour of modeling RC SLAB

Dear all....

Iam modelling and analysing a simply supported RC slab with ABAQUS CAE through Concrete Damaged Plasticity. The results show poor curve beyond the elastic region. The load vs central deflection graph shows very low curve at plastic region, which is far away when compared to experimental test result. I have tried many options for tensile behavior but still give poor results. I have modeled concrete material using C3D8R elements and T3D2 Truss elements for steel reinforcement which are embedded into concrete.

Please let me know what is the ideal data or equations or expression to relate the tensile behavior of RC Slab.

ABAQUS defines the viscoelastic properties also using a Prony series for
the shear and the volumetric response. It should therefore be possible
to convert the ABAQUS parameters to ANSYS format.

### Abaqus errors

I have confronted to errors that I dont know how can I resolve theme, as follows:

The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoRotInert have no rotary inertia associated with them and the rotational degree of freedom of the reference nodes is not restrained. Either rotary inertia must be defined at the reference node or the rotational degree of freedom of the reference nodes must be constrained. See the status file for further details.

and

The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoMass have no mass associated with them and some degrees of freedom of the reference node are not restrained. Either mass must be defined or all of the translational degrees of freedom must be constrained. See the status file for further details.

Hello ma'am,

I am Swapnil student of VJTI India, doing project in "Measuring stress relief in concrete due to Incremental core drilling". For this I have too model a column in which a core will be drilled in a structural element. I wanted to know how I can analyse a model which is continuously remain loaded during the coring process and will give results in terms of stress/strain at specific increment of coring procedure.

For. e.g column is loaded for a certain load and is having certain stress level, i'll remove a increment of 75 mm diameter of 5 mm thickness and see the effect on stress in column, i'll repeat this procedure for more number of increments successively in co relation with previously obtained results.

What type of procedure i need to employ for modelling ???

### modeling underwater explosion

I want to model underwater explosion in Abaqus. there is an example in abaqus help by the name of "9.1.3 Response of a submerged cylinder to an underwater explosion shock wave" which is very similar to what I'm trying to model. the problem is that i apply incident wave(planer/spherical/Undex) on the both structure and acoustic medium but i couldn't submit the model and it says " the model attributes wave formulation type must be set when using an incident wave interaction (Int-1 for example)"

I wolld appreciate it if anyone could help me with this. thanks.

### Re: modeling underwater explosion

This is in response to your e-mail.

I have never used Abaqus to run this sort of simulation.

Also, I don't understand what you mean by "i apply incident wave(planer/spherical/Undex) on the both structure and acoustic medium".

I suggest you take your problem to your Abaqus customer support person.  If you don't have customer support, you will have to be more detailed and explicit if you expect free help from people who are not working on exactly the same problem as you.
