Electromagnetic Forming Processes: Material Behaviour and Computational Modelling

Abstract : Electromagnetic Forming is a very promising high-speed forming process. However, designing these processes remains quite intricate as it leads to deal with strongly coupled multiphysics process and thus requires the use of computational models. We present here the main features of the numerical model which we are currently developing to model this process. Accurate knowledge of constitutive law parameters for material at high strain rates remains quite difficult to access. We thus introduce here a procedure which has been developed in order to deal with identification of these parameters.
