Hi all,

 

I am facing the following error in implicit nonlinear analysis. How to sort out the error?

 

 *** ERROR # 3019 ***
 TABLES1 bulk data entry ID=2 has a segment that corresponds to zero or
 negative hardening. This may lead to poor convergence and excessive
 plastic flow.

 

 

 

 

Regards,

Arul

    Hi Arul,

     

    this error is because the data points in TABLES1 ID=2 must be in ascending order.

    Stress values should not be the same- they should be increasing.
