SIF Accuracy - Abaqus XFEM

Hello,

I understand from word of mouth, as well as an extensive study/Master'sThesis (http://publications.lib.chalmers.se/records/fulltext/164269.pdf), that Abaqus XFEM formulation works, but that processing of results to obtain reported SIF (KI, KII, KIII, not sure about J, others) are in error due to apparent bugs in Abaqus's algorithm to calculate the SIFs.

problem with print*,"..." in VUMAT

Submitted by IUT student on Mon, 11/19/2012 - 19:01

my problem is that when I use print command in my subrutine VUMAT ,the results changes and sometimes abaqus stops with an error.

do you think is there any problem with my VUMAT or this problem is a routine problem with VUMAT subroutine?

thnaks for your help

vumat problem

my problem is to define initial value for solution dependent state varibales in Vumat.when I define them in .log file the same as help,it doesn,t work and the error is your'e defining initial condition for element zero while this elemet doesn,exist.what can I do for solving this prolem.

thanks alot

A review article of our research at IBM TJ Wason Research Center in piezoelectronic transistor, an exploratory device beyond silicon, is published in MRS Bulletin, Volume 37, Issue 11, November 2012, pp 1071-1076. Your future computer may depend even more on the mechanics.

ansys

I am doing simulation of fiber reinforced composites, for that I have modelled a cubic REV. However , when I am constraining the opposite faces' node displacement sum to be 0 and coupling the nodes in each face in the direction perpendicular to the area, ANSYS is coming out . I have tried this on i7 processor with 8GB RAM system. I am confused if its a RAM problem or a model problem. If there are too many constraints if I apply coupling as well as constraint???
