MaterialLib::Solids::MechanicsBase< DisplacementDim > Struct Template Reference

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.

pure virtual

Computation of the constitutive relation for specific material model. This should be implemented in the derived model. Fixed Kelvin vector and matrix size version; for dynamic size arguments there is an overloaded wrapper function. Returns nothing in case of errors in the computation if Newton iterations did not converge, for example.
