Mechanical Behaviour in DC Alloys Casting Processes

Abstract

The aim of this work is to give a review of algorithms computationally efficient to simulate the thermo-mechanical behaviour in casting processes; in particular, the butt curl deformation and the contraction of the lateral sides of the slab. The main aim is to give an overview of the most used methods to deal with the nonlinearities due to the thermo-elastic-viscoplastic laws of the involved materials and to the contact condition with the bottom block. To evaluate the efficiency of the proposed methods, some academic tests adapted to the difficulties arising in casting processes are presented. Applications of the techniques proposed to aluminium casting processes are discussed and numerical results are given.
