hello everyone,

I model a reinforced concrete column in ansys .
I want to know that in this picture what's meaning 'CP' , 'CP' is abbreviation of which Words and what's unit of that .

(Plz Download file to View the Picture)

thanks alot

Hello everyone

I model a reinforced concrete column in ansys .
after loading the model three types of crack will exist in it . ( First Crack,Second crack,Third Crack)
I want to know what difference between those .

is differences between those due to time of their existance or for other reasons  ?

If diffrence due to time of their existance , what criteria for time is considered ?

hi

could you give some suggestion ,which how can i use strand7 to analysis the membrance with  hole?

I was wondering whether CosmosWorks could help me solve this ( http://imechanica.org/node/5016 ) ?
I prefer to stay with SolidWorks because I already use it for 3D modeling so I guess it will be easier to learn,
but if necessary I would also consider software like Simulink.
What do you recommend?

Thanks in advance!

Hello everyone.

I need to apply a torsional load to the top face of a cylinder. I try doing this but my analysis doesnt run. I am using Abaqus 6.7 EF-1.

Can anyone help?

Hi

can Anyone help me to find johnson-cook failure model damage parameters(d1, d2, d3, d4) for Advanced hgih strength steels like DP and TRIP?

thanks

Hi everybody

I'm babak, and work with Abaqus.

that's so good too be up to date with Abaqus.

Dear iMechanicians,

While developing my own fatigue FEA-post-processor called PragTic (www.pragtic.com), I have got to a crossroad. PragTic have used quite sophisticated method for import of FEA data from formatted ASCII files, which allowed import of files from ABAQUS, ANSYS or COSMOS, with not that much problems. But, well it is definitely slower and e.g. for ANSYS more cumbersome. Also, it prevents adequate work with results on shells, because the information there gets too complicated (3D) due to existence of results on bottom and top sides of the element.

In fact, the only other solution in PragTic is a complete import of MSC.Nastran files (*.dat for topology, *.pch for results).

HI

I want to know how can I model a layered composite material(e.g. FRP or GRP) in ansys work bench 11? how can i define the material?

Just attended a FEMA introduction course put on by my provincial engineering assoc.  We all received a copy of Abaqus Student Edition.

When I install the program on my Toshiba Windows Vista laptop the installation completes but when I start the program and try to draw a part instead of getting a blue grid I get a second white drawing sheet overlaying the first.I have tried numerous installs and have all the latest Vista upgrades.  My copy of the DVD is good because the program works on my desktop computer. 

Abaqus do not provide any support to SE users.  Has anyone seen this problem and figured out a fix?

Hello,

I have to model with the Ansys software a beam in concrete material. It must be non linear.

In materials properties, I can choose Materials models - Structural - nonlinear - inelastic - non metal plasticity - concrete.

I put the Elastic Modulus, the Poisson´ratio, the uniaxial cracking stress and the uniaxial crushing stress. But I don´t know how I can enter the values of the strain at fc (compressive cylinder strength) and the value of the fracture energy.

Can you help me even if you don´t know exactly how to do... some advices can be really welcome.

Thank you.

The plot is showing a value typically obtained at the integrations points (in this case a single integration point).

Normally you would make a plot like this by taking the mean value of the surrounding elements to each node, then making a interpolated plot like this. However, it is obvious this is not the case around the red node, as it has several different values in the same node.

This behaviour happens quite often for me in ABAQUS/CAE, and it is quite annoying as the strange looking plot makes the results seem less trustworth.

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. 

While meshing the cylinder,
I realized that I can't seed the surface area of the cylinder, only the
circumference of the top and down circles can be seeded., and after meshing the part the surface area of the cylinder is assigned elements automatically according ot the number of seeds on the circles.

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.

I'm trying to eidt abaqus inp file using matlab, without opening the editor/debugger. Any help would be appreciated.

Hello all friends here:
      I want to ask a question:
"How to deactivate solidworks2008 license in one PC and then transfer to another PC? Are there any instruction I could follow?"
      If some friends know how to do this, could you please do me a favor?
      Highly appreciate.

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 ...

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

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

Holidays are coming, and you might have time to play around with new things.  Here is something really cool and really useful.  Early this year, Daniel Suo introduced me to a new online service, Dropbox.  Once you place a file in Dropbox on your computer, the service remembers the file online when the computer is connected to the Internet.  Subsequently, when you connect another computer to the Internet, Dropbox synchronizes the file for you.  The file now exists on both computers.  You can access the file rapidly even when both computers are offline.  The file is synchronized again once you go online.  I have been using Dropbox to synchronize files on my laptop at home and my desktop at work.

DEAR,SIR HOW CAN I MERGING (NODE)OF A PLATE ELEMENT (SHELL 99)AND A BEAM ELEMENT IN ANSYS SOFTWARE.

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.

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?
