Résumé

Cellular solidmaterials and,more specifically, foams are increasingly common inmany industrial applications due to their attractive characteristics.Thetetrakaidecahedral foammicrostructure,which can be observed in many types of foams, is studied in the present work in association with shape memory alloys (SMA) material. SMA foams are of particular interest as they associate both the shape memory effect and the superelasticity with the characteristics of foam. A Unit Cell Finite ElementMethod approach is used, an approach that allows accurate predicting of the macroscale response of the foam with a highly reduced numerical effort. The tetrakaidecahedral foam’s responses, both in the elastic and in the superelastic stages, are then extracted and compared with results fromthe literature.Thetetrakaidecahedral geometry is found to be of particular interest when associated with SMAas it takesmore advantage of the superelastic property of the material than foams with randomly distributed porosity.
