Dear all

I want to start modeling the Hyper foam behavior in abaqus software, it is very usefull for me to consult with someone who works on that.

Iterations in VUMAT

Submitted by cece83 on Thu, 12/03/2009 - 17:23

Dear all,

I' m trying to make a model in VUMAT for shape memory alloy based on Lagoudas 's thermomechanical constitutive model. It seems that It's necessary an iteration to evaluate the thermoelastic prediction.

My questions are : is it possible to use an iterative loop in the VUMAT or it's better to avoid it??Could someone suggest me a different way so that I can avoid the iterative loop?

Many thanks,

Cece

Importing ONLY Damage and Displacement in an Analysis

Abaqus/Standard import

Hi, i've got the following Problem:

I am running an Abaqus/Standard Analysis in which i am importing the results from a previous Explicit Analysis.

The thing is, I only want to Import the deformed mesh (displacement) and the damages to my model.

I tried using the "Predefined Field" option, but this imports every result from the previous analysis.

Is there any way I can choose which variables to import (e.g. U3,...) ???

Thanks for any help!

Dynamic failure analysis with ansys

Submitted by ranganel on Wed, 12/02/2009 - 20:09

I would like to perform a dynamic structural analysis with ansys.

How can I include in the analysis a check after each time step about the status of some elements ( check whether they are broken)

"kill" them if need to and continue the analysis.

Thanks,

Ran
