WebPLSLIMIT — Maximum equivalent plastic strain allowed within a time-step (substep). If the calculated value exceeds VALUE, the program performs a cutback (bisection).Default: VALUE = 0.15 (15 percent) If CUTCONTROL with Lab = PLSLIMIT is not issued, the minimum time step specified is reached, and the maximum plastic limit calculated from … WebIn ansys there are four convergence criteria (force, displacement, moment and rotation). When you use one of them, you may specify a value, a tolerance and a minimum …
