force-deflection full hysteresis loop
Modelling a square plate (surface body) using multilinear plastic material, undergoing a repeated pressure pulse as below and fixed support B.C. is applied to the four edges, I can not extract the hysteresis loop in a way I can read the permanent deformations after each pulse. I'm looking for some hints , please.
Here is the hysteresis loop I get using total deformation and force reaction results:
