Hi,
I have computed the constants in the Johnson cook constitutive model (not the damage model) using my test data.
I have not yet computed the constants in Johnson Cooks damage model.
I want to carry out a simulation of tension test and compare experimental vs FEA results and then improve my model (or constants). I'm using LS Dyna for simulation.
Can I forego the damage model and test the constutive model?
Any help to carry out this simualtion will be appreciated

You should be able to
You should be able to compare the results without the damage model up to the point at which your specimen began to fail.

application of large strain theory to Johnson cook model
Hi
I had some issues with how the johnson cook constutive model behaves with the large strain and small strain. I need some guidence in this subject for me to debugg this johnson cook model
