Thermal Expansion (for Constraints)
Add the Thermal Expansion subnode to a constraint (Fixed Constraint, Fixed Constraint, Interface, Prescribed Displacement, or Prescribed Displacement, Interface) to prescribe a deformation of the constrained boundary caused by changes in temperature of the surroundings. This makes it possible to reduce the stresses caused by such boundary conditions.
The thermal strain depends on the coefficient of thermal expansion α, the temperature T, and the strain-free reference temperature Tref as
Layer Selection
Select the layer or interfaces based on this node is added under which type of constraints feature. You can select individual layers or interfaces in this node which are allowed on the parent node.
All other settings for the Thermal Expansion node are described in the documentation for Thermal Expansion (for Constraints) in the Solid Mechanics interface.
