2. Core temperature and thermomechanical couplings
In this section, we analyze the thermal evolution at the heart of the part.
2.1 Fast flows: adiabatic coupling
First, let's look at the case of rapid or very short-duration flows.
SCROLL TO TOPIf plastic flow takes place in a very short time, heat exchange by thermal conduction with the environment can be neglected, and the material element fully retains its deformation energy and the associated heating: the flow is said to be adiabatic. A quantitative...
