Detailed Description

Todo
Update documentation

Abstract base class for all lattice "structural" constitutive models. It declares common services provided by all lattice structural material models. The implementation of these services is partly left on derived classes, which will implement constitutive model dependent part. Structural material services should not be called directly by elements. Instead, they always should pass their requests to corresponding cross section model. Cross section performs all necessary integration over its volume and invokes material model services.
