The Linear Thermoelastic Material node adds both the structural and heat transfer equations to the solid, in addition to the thermoelastic coupling. The
Initial Stress and Strain, and
Damping subnodes are available from the context menu (right-click the parent node) or from the
Physics toolbar,
Attributes menu.
The Equilibrium Temperature T0 input defines the equilibrium temperature for the stationary solid. If there are temperature dependent material properties, this value defines their evaluation point. Other model inputs appear if the material properties depend on other quantities.
The default Coefficient of thermal expansion α (SI unit: 1/K) uses values
From material. For
User defined enter a different value or expression and then for the Linear Thermoelastic Material, select
Isotropic,
Diagonal or
Symmetric and enter one or more components for a general coefficient of thermal expansion
α.
Enter a value or expression of the Strain reference temperature Tref (SI unit: K), which is the reference temperature at which the stationary solid is unstrained. If there are no initial thermal stresses, this value should be set to the same number as the Equilibrium Temperature (in the Model Inputs section). Setting a different temperature includes thermal stresses in the model, in addition to the thermoelastic stresses. The default is 293.15 K.
The default the Thermal conductivity k (SI unit: W/(m·K)) uses values
From material. For
User defined select
Isotropic to define a scalar value, or
Diagonal,
Symmetric, or
Anisotropic to enter other values or expressions in the field or matrix. The default is 0 W/(m·K).
The default Heat capacity at constant pressure Cp (SI unit: J/(kg·K)) is taken
From material. For
User defined enter another value or expression in the field. The default is 0 J/(kg·K).
