Courses
Multiscale modelling in mechanics
Ce cours présente les principes et techniques de modélisation des matériaux à différentes échelles spatiales, depuis le niveau des atomes ou des grains jusqu'à l'échelle continue ou structurelle. L'accent est mis sur la mise à l'échelle hiérarchique (homogénéisation), tandis que les techniques concu
Soil mechanics and flow through porous media
Le cours présente les principes fondamentaux de la mécanique des sols et des milieux poreux infiltrés par des liquides. La première partie est consacrée au comportement constitutif des sols dans des conditions sèches, tandis que la deuxième partie explique la présence d'eau interstitielle.
