Hello everyone，
I have realized the bar necking case from the munual of Comsol. I think I can use this successful case as a basement to realize my consititutive model. But there are lot of errors in the result.
My hardening model is as below.
Where the k=400 MPa, sigma0=200 MPa, n=0.2.
I wonder for my hardening model if I can simulate the necking phenomenon using Comsol.
