✦ Synopsis

In order to model thixoforming processes, previous papers presented a thermomechanical one-phase modelling. This first version of the constitutive model revealed several limitations: the model could not degenerate properly to pure solid or liquid behavior nor to free solid suspensions. The aim of this paper was to propose solutions to overcome these limitations.

The pressure-time history of a deployed airbag provides the basis for the restraint created by this safety system. A simple numerical simulation of this pressuretime history was developed based on our understanding of the various factors that influence the restraint performance. The general interact

The goal of this paper is to analyze analytical and numerically, from several perspectives, the modulus of rupture (MOR) for brittle materials, studying the bending test of three points which is normally used in laboratory to calculate it. In particular, we will give four different approaches to the
