• ThermalFractureIntegralCalculates summation of the derivative of the eigenstrains with respect to temperature.
• TwoPhaseStressMaterialCompute a global stress in a two phase model
• VolumeDeformGradCorrectedStressTransforms stress with volumetric term from previous configuration to this configuration
• WaveSpeedComputes an approximate wave speed from the material stiffness and density
