HI
I have a problem about modeling of post buckling in ABAQUS. Despite the fact that I can model of post buckling with imperfection in ABAQUS, I don't know how to plot strain-force diagram this phenomenon after post buckling with output data the same as strain-force plots in every solid mechanic books. I have problem When I try to plot nonlinear area in diagram after post buckling, obviously, if I decrease load after post buckling , I must observe that strain will be increased by decrease load but when I decrease load in ABAQUS. proportional load has derceased!! If you solve my problem I appreciate you.
Best regards
