Detailed Description

template<int DisplacementDim>
struct MaterialLib::Solids::MechanicsBase< DisplacementDim >

Interface for mechanical solid material models. Provides updates of the stress for a given current state and also a tangent at that position. If the implemented material model stores an internal state, the nested MaterialStateVariables class should be used; it's only responsibility is to provide state's push back possibility.
