Keywords:
modelling, numerical simulation, finite element method, coupled problem, induction hardening process, magnetodynamics, thermo-metallurgy, thermo-mechanics, residual mechanical stresses and strainsAbstract
Coupled non-linear magnetodynamic and thermal phenomena characterize the induction heating. Its modelling classically rests on the indirect method which consists of several analyses which are performed alternatively. This method can be replaced by another one called direct method such that the temperature and the different harmonics of the unknown electromagnetic quantity are calculated in a same finite element. This new method has been previously presented and the following intends to show in an example that the accuracy of metallurgical, thermal and mechanical results depends on the number of harmonics which are calculated.
