Hello Hamid Reza Attar ,

Basically, there are at least three methods to perform such task. The problem is that most of them works only for Explicit anylysis. Below is a brief description of them all.

1) Using *FILTER "to stop the analysis when the value of any variable in the output request reaches a specified upper bound or lower bound".

Works ONLY with Explicit analysis.

2) Using *EXTREME VALUE with *EXTREME ELEMENT VALUE "to stop the analysis at the first occurrence of a variable exceeding its user-specifed bound"

Works ONLY with Explicit analysis.

3) Using utility routine XIT "within any Abaqus/Standard or Abaqus/Explicit user subroutine, respectively, to terminate an analysis."

You need to include this command in some user subroutine which would check the PEEQ value, and if it reach some extream value, run the command XIT. I would recommend to use USDFLD subroutine with utility routine GETVRM for Abaqus/Standard.
