Hi, <\/p>\n

I managed to solve this multi-step static and fatigue analysis although it took quite a while (+7h):<\/p>\n

<\/p>\n

 <\/p>\n

Now I just want to repeat exactly the same analysis but with a different plasticity model for the chosen materials (it was bilinear isotropic hardening before and I changed them now to kinematic hardening) keeping everything else the same.  However the convergence troubles appear at the very beginning where before was a smooth and easy go…:<\/p>\n

<\/p>\n

 <\/p>\n

Any idea why or what am I missing?<\/p>\n

Thanks<\/p>\n","protected":false},"template":"","class_list":["post-275370","topic","type-topic","status-closed","hentry","topic-tag-convergenceerror-1","topic-tag-plasticity"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
