A One Phase Thermomechanical Model for Semi-Solid Thixoforming

Abstract:

In order to model thixoforming processes, previous papers presented a thermomechanical one-phase modelling. This first version of constitutive model revealed several limitations: the model could not degenerate properly to pure solid or liquid behaviour neither to free solid suspensions. The aim of this paper was to propose solutions to overcome these limitations.
