Increamental plastic strain is too large

Question asked by Thulani Sobekwa on Nov 12, 2015

Good day,

 

I am running this nonlinear static study. It runs up to 19%  (step 6), then the warning massage pops "increamental plastic strain is too large; Autoomatic reset".

Then it adjust itself according to the number of allowable adjustments, eventually the study fails.

 

I tried to adjust my stepping options by decreasing the initial time increment and the max. increment, it did'nt work. Now I am wondering where the problem is, could it be the mesh quality or anything else?

 

Any suggestions please.

 

Thanks,

Thulani Sobekwa
