Abstract
Analytical calculations of thermal residual stresses around an inclusion are valid only as long as interactions between inclusions are negligible. Now current volume fractions of ceramic particles or microfibers in metal matrix composites are not diluted. Finite element modelling, using the MARC code, coupled with an original numerical homogenization technique can take these interactions into account, giving relevant information on the level of thermal residual stresses and a mapping thereof. This technique is used in order to assess the influence of ceramic inclusions’shape as well of different cooling paths on the thermal stress Held. It emerges as a computation tool for understanding mmc’s or other diphasic materials’ behaviour and defining adapted thermomechanical treatments thereof
