Simulation of Semi-Solid Material Mechanical Behavior Using a Combined Discrete/Finite Element Method

Michel Rappaz, Jean-Marie Drezet, Meisam Sistaninia

As a necessary step toward the quantitative prediction of hot tearing defects, a three-dimensional stress–strain simulation based on a combined finite element (FE)/discrete element method (DEM) has been developed that is capable of predicting the mechanica ...

PYROMEMS IGNITER BASED ON A TEMPERATURE GRADIENT: CONCEPT, FABRICATION AND CHARACTERIZATION

Nico de Rooij, Danick Briand, David de Koninck

A pyroMEMS igniter with increased combustion reliability is presented. The igniter consisted of a thin-film platinum Joule heater fabricated on a borosilicate glass substrate. Two different igniter layouts (meandering and annular) and three different binde ...

A new tensile test for aluminum alloys in the mushy state: Experimental method and numerical modeling

Michel Rappaz, Vincent Mathier

A fairly simple experimental setup has been designed for testing the resistance of the mushy zone of alloys during solidification under tensile conditions. It has been used to study the effect of coalescence among the solid grains at a late stage of solidi ...

Film stacking impregnation model for a novel net-shape thermoplastic composite preforming process

Jan-Anders Edvin Maansson, Véronique Michaud, Martyn Douglas Wakeman, Simon Jespersen

An impregnation model has been developed to evaluate the infiltration phenomena that occur during a novel near net shape preforming method. This process comprises automated deposition of thermoplastic resin and unidirectional (UD) carbon fibres to a pre-pr ...
