Looking for material to control unloading strain

Post by structurestudent » Fri Sep 03, 2021 12:55 pm

I am looking for a material that enables us to control the ε0 as 0.3 times maximum ε as shown in the picture below.

There are some materials in which we can control the unloading slope, but is there any material we could control ε0 equal to 0.3 times maximum ε?

I would like to ask for any advice.
Thank you
