Error while using MATS1 & TABLES1 Card in optistruct

Arul

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.

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.
