    Description:Stress free temperature

  • temperatureNonlinear variable name for the temperature

    C++ Type:std::vector<VariableName>

    Controllable:No

    Description:Nonlinear variable name for the temperature

  • thermal_expansion_coeffValue of material thermal expansion coefficient

    C++ Type:double

    Controllable:No

    Description:Value of material thermal expansion coefficient

  • use_interpolated_stateFalseFor the old and older state use projected material properties interpolated at the quadrature points. To set up projection use the ProjectedStatefulMaterialStorageAction.
