[Question #699346]: How to simulate the material with big elastoplastic property such as PLA

 

New question #699346 on Yade:

I am simulating the material with big elastoplastic property. The stress-strain curve of the material has the normal elastic characteristic, but it will tend to be stable after the yield stage showing that it has a big plastic characteristic and  there is not a strain softening stage. The material is just like PLA. My question is what material and constitutive law are supposed to be used properly. Is there any example for it?
