force-deflection full hysteresis loop

      Hi,

      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.

      nActually yes!nI want to export the permanent deformations of the model after each load, but I'm quite a beginner and couldn't exactly find out what was going on!nDo you suggest to apply isotropic hardening to the material modelling? n

      No, I suggest you use the Chaboche model. n

      nShall I used Chaboche model besides my previous settings (multilinear isotropic hardening) or ignor the previous settings?n

      Charboche replaces multilinear isotropic hardening.n

      nShall I use the values used in the post you previously mentioned or find them somewhere else?nI want to model Al 5083_h116n

      Use values that are for the material you want to use.n
