Theory for the Thermal Stress Interface
In the Structural Mechanics interfaces, two multiphysics interfaces handle thermal stress:
•
The Thermal Stress, Solid Interface
•
The Joule Heating and Thermal Expansion Interface
Both require the Structural Mechanics Module. They have in common the use of the Thermal Expansion multiphysics coupling that models temperature dependence of the strain tensor and thermoelastic damping. For more details about the underlying theory, see the Structural Mechanics Module User’s Guide.
