Hi.
In elasto-plastic modeling , we need data like this :
yield stress(or strenght.any difference?) plastic strain temperature
.
.
.
what is plastic strain?at yield plastic deformation begins so at yield plastic strain is zero (Abaqus ask to set the first plastic strain to zero!)
but i say at each temp, it should be zero!
for example if at 25c aluminum 1100 yields at stress=x,at this point plastic strain is zero and if at 300c it yields at stress =y , then the plastic strain is zero again at that point!
is it total plastic strain?where can i find data for it. for aluminum 1100 for example.
thanks for your attention
