Abaqus CAE

I intend to create a
composite model, containing a cylindrical fiber surrounded by a cube,
by Abaqus CAE v 6.7-1. I create
two separet parts, one for the cube and the other one for the cylinder. Then, I
cut the cube by the fiber; the third part (lets say the cut part) is created
automatically. Now, I need to mesh the parts and merge them. 

Loading X, Y, and strain data from multiple files in Tecplot 360

Dear All

 

I am using tecplot to visualize my data. Now I came across a problem as I have three files (created using Matlab). Each file is having a big matrix having data. One file is having X coordiates, second one is having Y coordinates and third one is having the strain data of these two coordinates. I like to import and plot contour using this data. It will be nice if some one can guide me in this matter.

weld simulation

hi every body

nice to meet all of u

i am a metallurgical engineering. and recently i am trying welding residual stress simulation using abaqus .

i
have some problem .i think i should set a thermal history for the material
witch is welded in simulation. i want to know how can i set a temperature
dependant properties like tensile stress or  yield stress and ...

Compiling and Building TAUCS a library of sparse linear solvers

I would like to share the following information to all the iMechanica users interested in using TAUCS a library of sparse linear solvers. TAUCS is among the most used libraries of sparse linear solvers and, to my knowledge, its closest equivalent library is SuperLU. For your reference, TAUCS is used in the commercial software Mathematica by Wolfram Research. Its source code can be downloaded from

Regarding ABAQUS installation

Can any body help me regarding abaqus v6.7-3 installation. I am facing problem while installing the abaqus product. It asks license server 1. As I enter there 27000@host ID a massage comes that

"there was a problem constructing the value for the abaquslm_license_file parameter to be entered in to your abaqus_v6.env file. Please enter the value for this variable exactly as it should apear in the environment file"

Plz help me regarding this problem

op2 from MSC Marc?

Dear iMechanicians,

I wonder if anybody knows how to get an op2 file (MSC.Nastran) from MSC.Marc. Is something like that possible? Or do you know some available converter? Potentially, fil or odb file from ABAQUS or rst file from ANSYS could help as well. But I would expect there some way within the MSC product family...

Thanks a lot for any idea.

how to define cyclic load using abaqus

Choose a channel featured in the header of iMechanica: 
Free Tags: 

hello everybody:

i am trying to do a project on load controlled cyclic test. By using the Sin wave, i want to define the load.

If i want to define the load range to be 100 to 1000 how can i define the amplitude?

Also, as come to the platic deformation, do i need to give any criterion or anything particular?

thanks

anyone has some idear can you send to xiaojiao_yu@brown.edu?

VUMAT and ALE in ABAQUS

Hi all,

     Here I encoutered a error in ABAQUS when I include ALE with VUMAT. When ALE was not included with VUMAT, my job can work well while with the combination of VUMAT and ALE, the job cann't work any more due to a "Signal 8" error. And if I use a built-in material model and at the same time ALE, a job can work. Furthermore, element failure is considered in all of the cases.

    Anyone can give some suggetion? Thanks in advance!

ALE in ABAQUS and LSDYNA

Hi all,

     Can anyone give a description on the diffrence of ALE in ABAQUS and LSDYNA? And also the difference between r-adaptivity and ALE in ABAQUS. It seems ALE in ABAQUS means the same with r-adaptivity in LSDYNA while “ALE” means diffrently in the two codes.

      Thanks a lot!

When and where the stress objective rates are used in ABAQUS software?

Hi everyone,

    I have a question about the objectivity tensor in ABAQUS software. Below is my question.   

What is the best software

I see that people talk a lot about ANSYS over here and that is the software that I use during my works at university. However, when I read some papers or attend some conferences I hear about other finite element programs such as ABACUS and NASTRAN. Besides that I've also seen other open-source codes such as SALOME, Code-Aster, etc...

What do you think is the best software to make finite element analisys, or if it's difficult to say wich one is best, what are the weak and strong points of each software? 

Abaqus/Explicit VUMAT tensor components ordering

Hello everyone,

 

I am coding a VUMAT for Abaqus/Explicit. I was wondering if the tensor components ordering was ALWAYS different from the one used in ABAQUS/Implicit, or if the special ordering was valid only for the C3D8R element.

crack in abaqus

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 ?

Thanks in advance.

Ask for contact problem in ABAQUS?

Choose a channel featured in the header of iMechanica: 

Hello all,

I'm modeling the railways track system, in which the rail wil be  affixed to the cross tie by Fastening to against the vertical force. 

Now instead of modeling the Fastening, I would like to model the contact between Rail and cross Tie in ABAQUS. I have try surface to surface; surface to node and also tie constrains, but somehow  the results are not reasonable (not agree to experiment result). I thinks the problem is contact properties.

So are there any one can helo me on the problem?

ANSYS qu from new user: help me write a "for" loop please!

Hi: I am a new ANSYS user and would really appreciate help writing a "for"-type loop to go with an example found here:

http://www.mece.ualberta.ca/tutorials/ansys/CL/CAT/BirthDeath/Print.html

 At the end of the example is the paragraph below.  I want to know how to do this!  Can anyone modify the code for me?  I don't even know where to start.  I would be very grateful!

 I am doing a laminate composite in ABAQUS. Is there any titurial I can learn from?

 Thanks

calculation of Stress in composites

Hi engineers,

I am working in fiber composites with ABAQUS, but I have a problem,

I can't calculate stress and other element variables, can you help me ?

Too,I have to use ABAQUS/CAE for model and here is my *.inp file.

Thanks for your help
