SubscriberHello,
I am trying to simulate a projectile impact onto a plate in LS-DYNA, and have been using the Johnson-Cook criteria for failure. However, when I run the simulation, it does not show fracture or damage the way I would expect. Instead, it simply stretched the plate. Is there a parameter that I might have missed?
The materials selected for the plate are aluminum and titanium.
Thank you.

Ansys EmployeeHi Joshua,Â
can you post your material card here ?, Did you define D1-D5 parameters ?, Are there any additional failure criteria defined?
Is the strain rate in your model enough to progress to failure?
Cheers, RamÂ

SubscriberHello,
I managed to solve it. I didn't fully define some settings in the failure criteria.
Thank you,
Joshua Monsey
