Trying to run a simulation in explicit dynamics and everything was going fine, ran a nice simulation of a ceramic armor plate of Alumina and UHMWPE. Then I discovered that I entered a value into the Alumina incorrectly which is why the entire ceramic was failing at impact. Fixed that, ran it...
Getting pretty frustrated trying to figure out how in the world to input material data for fiber composite materials, specifically UHMWPE, without ANSYS having a stroke saying "the Hydro strength can only be used with Hydro failure" or the EOS and strengths are incompatible. Attached is a copy...
I am trying to analysis a bullet vs armor situation in AutoDyn and it comes out mostly correct although the bullet doesn't seem to be realistically simulated and I am concerned about it. Attached is the .MP4 file of the animation generated from the results. Notice how the entire bullet breaks...
