C++ Type:std::string
Controllable:No
Description:Name of the parsed material property
ElasticEnergyMaterial
Free energy material for the elastic energy contributions.
This material generates an elastic free energy contribution consistent with the TensorMechanics stress divergence kernels. This allows for proper coupling of the phase field problem and the mechanics problem. The contribution of the ElasticEnergyMaterial
and the chemical free energy (possibly defined using a DerivativeParsedMaterial
) are then summed up using a DerivativeSumMaterial
to form a _total free energy_ which is passed to the phase field kernels.
The ElasticEnergyMaterial
applies a _linear_ elasticity model. It couples in the strain and the elasticity tensor to compute the elastic energy
The material utilizes the derivatives of and to provide the derivatives of , which are required by the phase field equations.
