Summary

The course aims at providing future civil engineers with the knowledge of geomechanics for professional practice. It addresses, among others, the main stress-strain constitutive models within the context of elasticity and elasto-plasticity and the estimation methods of the lateral earth pressure.

Content

Stress-strain behaviour of geomaterials in drained and undrained conditions

Laboratory tests with special focus on triaxial testing

-          Elasticity

      Linear and non-linear elasticity

     Applications of elastic models

-          Plasticity

Plasticity principle and yield criteria for geomaterials

Critical state concept

Elasto-plastic stress-strain constitutive frameworks (among other Modified Cam Clay model)

Real cases and time-dependent phenomena

Viscous deformations: basic concepts and experimental evidences

Visco-elasto plastic models

Basic concepts

Hydraulic and mechanical behaviour
