 i want some one to clarify fundamental definition ,inter relationship or difference between the following terminologies .

small strain

large strain

small scale yielding

large scale yielding 

Hi,

 Is there some fem code or software that can handle eigenstrain while solving equilibrium equation?

 Thanks!

Hi, 

I have a question on reading outputs in Abaqus. Is it possible to select apath using nodes without having to click on each node one at a time? Everytime I close Abaqus the path I create goes away and I have to create it again and again. 

Hello everyone,

I hope to find an answer to my problem in this forum.

I'm working on the finite element model of a SMP in order to predict the recovery shape after heating. I'm in trouble about the material properties of this kind of polymer. I run tensile stress test, DMA and TMA in order to characterise the material. However I didn't succeed to write the good command in Ansys to get a shape memory effect.

Does anyone of you has knowledges about SMP ?

Thank you very much,

Michel

hi every one

i have problems with abaqus incrementation , now i do fill min,max and initial increment by trial and error , its not efficiency when running time is much,i will be glad if any one can help my and give me overlook of abaqus incrementation.

thanks 

I am using Smoothed Particle Hydrodynamics (SPH) with dual particle
approach (please look at the figures in the .ppt file I have attached) to simulate High
Velocity impact phenomena.

The shape function values being 1 at the corner particle and zero at the other particles makes the Jacobian to evaluate the gradients of shape function inconvenient (the jacobian becomes a zero matrix). 

The slides explain my problem more clearly.

Kindly go through them and help me.
