ANSYS Mechanical FEA

Created by Yohann Panthakee on 26 December, 2018

Hey guys! I need help with one of my analyses in LS-DYNA.

The project is bullet impact on a wall. Bullet has nonlinear Titanium alloy and the wall has modified 1006 steel (modified in johnson cook strength material properties etc.).

The problem is the bullet stops before hitting the wall even though I changed the end time from 0.00008 to 0.008. It takes more time to solve every time I increase the end time. So I need an exact solution for this.

Any ideas?
