Sapphire is an anisotropic crystal .  

How to set elastic constants in abaqus ?

How to get the shear stress on some special plane ?

In abaqus ,  there is an example for SPH. It can be obtained by:

abaqus fetch job=ver_prc_projectileimpact.inp

There are two fracute criterion in this file.

But even both of them are removed, the simulation results are similar.

Why?

In SPH method, does it need fracture criterion?
