Modeling of Semisolid Flow
Chapitre d'ouvrage scientifique
Résumé
Numerical simulation of semisolid processing can be carried out using one- or two-phase modeling. Various models based from either fluid or solid mechanics formalisms were developed. The most sophisticated one-phase models account for shear thinning, thixotropy, and solidification/melting phenomena. They are of great interest to investigate the flow front and optimize die geometry, temperature of die, and billet. Liquid-solid segregation prediction requires two-phase modeling. Basic equations and constitutive models currently used for numerical simulation of semisolid processing are presented and discussed.

Since always, Industry minimizes manufacturing process plan and increases mechanical behaviour. In this topic, the thixoforging process offers important perspectives especially steel thixoforging. It is on the way of ... -
Article dans une revue avec comité de lectureThe present paper focuses the modelling and the simulation of a direct thixoextrusion test achieved on C38 semi-solid steel. To validate the modelling and the simulation, it is important to get various experimental ...

Steel thixoforging process combines the advantages of performing parts having highly complex shapes and good mechanical properties. These advantages result from the shear thinning flow behaviour of semi-solids due to ... -
Article dans une revue avec comité de lectureVery high cycle fatigue carried out on pure copper polycrystals promotes early slip markings, labelled as slip markings of types II and III, localized close to grain or twin boundaries. In this work, we focus on whether ...

This paper presents an experimental device developed to detect and estimate dissipated energy during very high cycle fatigue tests (VHCF) at high loading frequency (20 kHz) and low stress (i.e. far below the yield stress). ...
