1. Thermomechanical equations

First, we'll determine the equations relating to the mechanical and then the thermal problem.

1.1 Putting the mechanical problem into equation

  • Fundamental principle of dynamics

    Mechanical equilibrium is written using the fundamental principle of dynamics. For a continuous medium, it means that the resultant of all forces applied to an element of material volume (volumetric forces, external forces and inertial forces) is zero, whatever the element under consideration. Let's consider a medium subjected to a volumetric force ρg (with...
