Elasticity Matrix

Hi

I have a question regarding material parameter of Si3N4.
In the library it is mentioned that "Elasticity Matrix" of Si3N4 is 100 Pa.
I just wondered How they calculate this value. Because I need to fill this for other material (Poly-Si) But I have no Idea where I can find It.

Regards
Bahareh
