4. Thermomechanical calculation: degree of coupling

The coupling of thermal and mechanical equations often makes them difficult to solve (lack of analytical solutions, convergence problems in calculation codes and excessively long calculation times). We therefore often seek to simplify these equations by reducing their coupling as much as possible.

4.1 Adiabatic phenomena

A particular thermomechanical problem frequently encountered is the case of rapid (dynamic) loading. A simplifying assumption is to neglect the conduction term λΔT in front of the heat power term ${ρc}_{V} \dot{T}$ . The problem is...
