Hi
I want to create a material looks like :

when start loading it will go from 0 to P under slope k1.
then it will have a plastic deformation D.
After D it will have continue with k2.
when unloading it will go back using slope k2 first ( like it is elastic ) and then behave like a elastic plastic material.
it is easy to play with parallel material to achieve the loading part but not so much about the unloading.
Does anyone has a good idea ??? I prefer to use the existing material model and save some time from creating a new material.
Best,
create this force displacement relationship material
