Degradations and Instabilities in Geomaterials

This book presents the most recents developments in the modelling of degradations (of thermo-chemo-mechanical origin) and of bifurcations and instabilities (leading to localized or diffuse failure modes) taking place in geomaterials (soils, rocks, concrete). Applications (landslides, rockfalls, debris flows, concrete and rock ageing, etc.) are discussed in detail.

Modelling the various failure modes in geomaterials (soils, rocks, concrete): from theory to applications Most recent developments for modelling bifurcations, instabilities and degradations in geomaterials are presented in the general framework of enriched continuum mechanics New views, methods and tools for medelling failure in geomechanics
