Hi all,

I am currently in my second year in Engineering school in France. I am doing research on 3D crack propagation in Rubber composites like tires.

And I wonder what is the best method to compute GI, GII and GIII. I have difficulties to choose between methods like EDI and VCCT for example.

I work in the finite strains case with static and dynamic. I also have difficulties to find papers on this subject with comparisons.

Can anyone please help me out with that

Thank You

Best Regards

Hello Guys,

 i am working on elastomers,i want to analysis the rubber hose with kevlar reinforcement,i dont know how to model the fiber in rubber model,and which element i should use,is anyone help me out.

 thanks

Abaqus Damaged Plasticity- problem with Strain Rate

Ask iMechanica

Hi All,

I am using Abaqus explicit to simulate a simple compression test on a concrete cube. The cube's bottom face is fixed, and the compression is given by giving a displacement to the top face. In order to simulate concrete material I'm using the damaged plasticity model.

stress analysis

Hi All, thanks in advance for any replies.

I am currently doing my Thesis on fast stress analysis using the boundary element method and specifically, adaptive cross approximation. I ofter come across the terms "single layer potential" and "double layer potential", i "know" what they are mathematically, i was wondering if anyone could give me an insight into what they mean physically, or just give a simple non mathematical definition? Thanks a lot, Ian.

A challenge to Mr. Koenemann

I am sure that several of you have followed Mr. Koenemann's posts with some interests.  For some it might be entertainment, and for others it might be like watching a car wreck.  In any case, several iMechanicians have attempted to convince Falk that his theories do not make sense.  We have all failed miserably at that task.  I am perhaps a bit slower than most, but it is clear to me that Mr. Koenemann will not be convinced by any physical or mathematical arguments.
