brittle rupture

Hello Altair team,

I should simulate the impact of an hammer drill bit on a concrete brick. I followed the radioss tutorial on your youtube channell but I can't manage to have my model working properly. The problem is that the bit go through the brick without breaking it. Should I define a contact between the bit and the brick? In addition, the model checker tells me that the P14 property is incompatible with the material law 10, the one that I used for the brick, how can I fix this?

Thank you very much,

Luca
