Recently, I am simulating a material in Abaqus 6.14 software; I used the Johnson-Cook plastic hardening Model (Elastic+Plastic hardening (A, B,n)) and by Static General Step. But when I used Abaqus 6.12, with same parameters Elastic (E, v) and Plastic Hardening Johnson-Cook (A, B, n), but when the job has been submitted for analysis , Error is “time increment is too large”.

I don’t understand. But I think the material Jonson-Cook has been improved between Abaqus 6.12 and 6.14.

Thanks for your attention
