Dear all,

I would like to run a tensile test under ls-dyna of a mild steel  and
apply a 7000 N load to the dog bone specimen on a explicite scheme.

Unfortunately, I
have wild deformations ( and an error) on the nodes on edges where the
load is applied, so can you please tell me what are the importants
constants (like time termination, mass scale,...) and how to perform a
perfect run?

Have a good day,

Thank you

M.

Hello,

Hi! 

Can anyone explain to me what is the meaning of pinching in reinforced concrete structures?

Thanks

Dear All,

Any step-by-step appraoch of using finite element for image processing

will be appreciated. I'm very much aware of finite element and want to

use it to solve an imaging problem,i.e. 

Find U given F(an image)  : >> AU = F .

Thank You. 

Hi

I needed a help regarding ansys macro. I need to process a text file and use the data of the text file for further post processing. Is it possible to exceute an exe file from ansys macro and to read external text file using ansys macro commands

Hi



I want to simulate a cylinder into a cubic and interaction between them when cubic is subjected to vertical pressure.

I simulated it with ABAQUS, and I run it successfuly. But there was no interaction between cubic and cylinder, and deformations in cubic because of vertical pressure did not affect on cylinder. Do anyone have any solution for this problem?



With regards

The images about model are attached.

I'm working on fracture mechanics for my undergraduate project. My advisor has asked me to simulate the crack growth in a CT specimen using ABAQUS. When searching for tutorials about XFEM based crack growth, I found these: http://www.matthewpais.com/2d-crack-initiation

Now my problem is that even though I did everything the tutorial asks me to do, when I submit the job, I'm getting a zero element size error. Can Anyone help me with this?

Any kind of help regarding this topic will be high appreciated.
