When calculated plastic strain is bigger than default, what should I do?

      Hi,guys, I met a problem, my simulation is about heavy-loaded case, material model is plastic-elastic model, for plastic model, I consider kinematic coupled with isotropic hardening.nFor the simulation, I noted that Ansys always told me that the calculated plastic strain exceeds the default value(15%) the program performs a cutback (bisection), but I can still get a result. nI have a question :should I trust this result? my sub load steps is controlled by Ansys. If the result should not be trusted, what should I do to fix this problem? n

      please try to use smaller time step size (turn on auto time stepping and input proper initial, min and max time step size). n
