IORDANOFF, IvanANDRE, DamienCHARLES, Jean-LucVIOT, PhilippeAbstract
La méthode des éléments discrets est présentée comme une alternative aux approches de type mécanique des milieux continus pour aborder certains aspects liés aux problèmes dynamiques, notamment la multi fracturation de matériaux fragiles. Des exemples liés à l’usinage des composites et au surfaçage du verre sont présentés. Une extension de la méthode pour étudier le comportement des mousses est ensuite proposée et imagée par des premiers résultats.
