Hello every one , 

In fact I'm crating a new material(PBT_GF30 : Reinforced short fiber material )  in Material Designer and to do that I need to put the plastic strain Vs stresses .  I used the known formula to do this conversion https://docs.google.com/spreadsheets/d/1ZKJdmswIPB-7Rw3j6I_6ganKS_MfIs5X/edit#gid=392220995

I was surprised to get this 2 curves because I suppose that the first point for the plastic strain=0 must be equal to the yiled stress . The formula used are shown below 

Thank you for your response
