Dear All,
I defined cohesive surface between grains boundary of my model which the Hunag plasticity subroutine is also used. I used stainless steel as material and the problem is that the traction-separation plot is not the one I expect due to CS properties and the maximum force that the diagram shows me is around 120e6 Mpa while I expect to see the value around just 120 Mpa.
Cohesive Behavior, eligibility=ORIGINAL CONTACTS
204600., 78692.3, 78692.3
*Damage Initiation, criterion=QUADU
1e-06, 1e-06, 1e-06
*Damage Evolution, type=DISPLACEMENT
1.955e-05,
*Damage Stabilization
0.1
The forces are defined in Mpa and displacement in mm. Does anyone know that how I can solve this problem?
Thank you,
Arman
