I have been trying to model damage of material under projectile impact.
During damage evolution in JC damage criterion,displacement at failure needs to be specified.
How to find the value ,i have went through abaqus documentation, it says area under stress strain curve divided by charecteristic length,
But we have different stress strain curves for different triaxialities for same material.
Help me regarding this
