Multiphysics Interfaces and Couplings
The Multiphysics Interfaces and Couplings chapter describes two multiphysics interfaces found under the Metal Processing branch when adding a physics interface:
•
The Heat Transfer with Phase Transformations interface combines a Metal Phase Transformation interface with a Heat Transfer in Solids interface. The coupling of the interfaces appears on a domain level, where produced latent heat from the (temperature-dependent) phase transformations gives rise to a heat source in the heat equation. Optionally, phase-composition-dependent thermal material properties can be used in the heat transfer analysis.
•
The Steel Quenching Interface combines an Austenite Decomposition interface with a Heat Transfer in Solids interface and a Solid Mechanics interface. There are two domain level multiphysics couplings: In the first coupling, produced latent heat from the (temperature-dependent) phase transformations gives rise to a heat source in the heat equation. In the second coupling, phase transformation strains that result from thermal expansion or transformation-induced plasticity (TRIP) are transferred to the Solid Mechanics interface as inelastic strain contributions for the computation of stresses. In the case of plasticity, the coupling also involves equivalent plastic strains and hardening functions. Optionally, phase-composition-dependent thermal and mechanical properties can be used in the heat transfer and solid mechanics analyses.
•
The Induction Hardening Interface combines an Austenite Decomposition interface with a Heat Transfer in Solids interface, a Solid Mechanics interface, and a Magnetic Fields interface. There are three domain level multiphysics couplings: In the first coupling, produced latent heat from the (temperature-dependent) phase transformations gives rise to a heat source in the heat equation. In the second coupling, phase transformation strains that result from thermal expansion or transformation-induced plasticity (TRIP) are transferred to the Solid Mechanics interface as inelastic strain contributions for the computation of stresses. In the case of plasticity, the coupling also involves equivalent plastic strains and hardening functions. In the third coupling, resistive heating from the magnetic fields are added as a heat source term in the heat equation. Optionally, phase-composition-dependent thermal, mechanical, and electromagnetic properties can be used in the heat transfer, solid mechanics, and magnetic fields analyses.
•
The Phase Transformation Latent Heat multiphysics coupling adds the latent heat that is produced during phase transformations, as a heat source term, to the heat equation in a Heat Transfer interface.
•
The Phase Transformation multiphysics coupling adds the transformation strains that are produced during phase transformations, as an inelastic strain contribution, to the equation for stress in a Solid Mechanics interface. The coupling also transfers stresses and the equivalent plastic strain from a Solid Mechanics interface to the coupled phase transformation interface.
