Time Effects In Geomaterials



Auteurs : Pereira Jean-michel .

Résumé

In this paper, time effects, seen as strain rate effects and creep phenomenon, on the mechanical behaviour of geomaterials are considered. Coupling between these effects and partial saturation of geomaterials is more particularly studied. An elasto-visco-plastic model, called RASTRA, is presented and validated from the comparison with experimental data.

Mots clés

Strain rate; Creep; Suction; Partial saturation; Elastoplasticity
