Hi all,

HI everyone,

I am actually pretty confused about how to determine the correct time step increment in ABAQUS in a non-linear analysis. I first faced this problem when I used Hashins damage to capture in-plane shear response of the composite . The response which is bilinear graph depends a lot on the initial time step I give for the analysis i.e., for some time steps there is no bilinearity , only a single straight line. This has led to great confusion in my mind whether my model has a problem or whether ABAQUS itself has this problem.

Hi, 

I'm trying to do simulation of a standard shear test of a composite specimen. Hence I'm using the composite layup  to create the section of my specimen. But I'm getting the following error no matter what i do. I have even tried the following tutorial but still I'm getting the same error. The link to the tutorial - https://sites.google.com/site/abaqus2010/tutorial_1/tutorial_1-3c.  

I'm stuck here. Any help would be appreciated. Thanks in advance :)

I have put a history output request of displacement of a set of nodes in my model but the history output request doesnt how up in the results tree. Please  help.

Thanks in advance ,

Hey guys,      

               I'm new to using subroutines. I have installed the Intel Fortram Complier v10.1 and using it for running the subroutine UMAT. I am first testing the umat subroutine for Isotropic elasticity as given in the abaqus manual for a single element with one integration point, but I'm facing the following error:

Unexpected error 193
