Linear Elasticity material and forces

[j-signorelli]

Hi @mov-rax-rbx,

This is more of an elasticity question than an MFEM-related one - the book Theory and Practice of Finite Elements by Ern and Guermond, Section 3.4 outlines well what ElasticityIntegrator implements -- it is for linear isotropic elasticity. Accounting for density would be including gravity which you mentioned, but would not be a part of ElasticityIntegrator. Ultimate compressive/tensile strengths and yield strength aren't part of the model. A good reference for understanding the elasticity aspect in more detail is The Linearized Theory of Elasticity by Slaughter.

@j-signorelli Thank you.
