How do I make Abaqus stop the simulation once a critical value of PEEQ has been reached?

Hello, I am doing a series of metal forming simulations in Abaqus. I want the simulations to automatically stop when a critical value of PEEQ (or some other variable) has been reached, in order...

Why does increasing strain hardening exponent result in less material necking?

Hello, According to the power law, Stress=K*strain^n. Could someone please explain why an increase in strain hardening exponent n results in less material necking from this equation? Please see...
