The main physical phenomena which can be coupled with the mechanical computation of metal forming processes are analyzed. Recalling the classical thermal coupling, it is shown that a stronger numerical coupling is necessary when localization of the deformation occurs. Several situations where we have mechanical solid and liquid interactions with thermal coupling are briefly mentioned. A more complete description of electro magnetic and thermal coupling is given in view of induction heating. Finally the case of multi scale coupling for metallurgic microstructure evolution is introduced.
