Development of Elastoplastic Strain Hardening Models of Soil Behaviour,The concepts of failure, flow rule, successive yield surfaces and hardening rules are recalled. The original Granta Gravel and Cam Clay models are presented and discussed. The basic structure of the work-hardening model of Lade is sketched. The strain-hardening model of Nova and Wood, together with

Slope Failure and the loss of controllability of the incremental response of a soil specimen subjecditions, multiple strain rate solutions are possible under the same loading increment. Drained and undrained cases for sand and clay slopes are considered. For rapid loading of sandy slopes, the latent instability analysis allows the reasons of catastrophic collapses of very flat slopes to be explai

Continuous and discrete modelling of failure in geomechanics,ion of Stability and diffuse modes of failure are particularly considered in this paper in a dual framework : continuum mechanics and discrete mechanics. With the assumption of continuous media and as an illustration, the experiments have shown that .-constant loading paths can exhibit non-localized

Micromechanical approach to slope stability analysis,l issues related to this kind of approach are discussed, by highlighting advantages and difficulties with respect to other (more common) methods..A particular attention is devoted to define procedures which are necessary for calibrating parameters. This point is addressed by introducing a micro—macr

Ageing and durability of concrete structures,apter, we start with the investigation of chemo-mechanical damage due to calcium leaching. We show that the fracture characteristics, namely the internal length in continuum models evolve with ageing. This observation is confirmed with experiments on model materials. Acoustic emission data and size
