Development of a elasto-viscoplastic model to simulate the solid-fluid transition: application to mudflows on the Vaches Noires cliffs, Normandy, France

Résumé

An elasto-viscoplastic model has been developed to simulate the solid-fluid transition by coupling two constitutive regimes: Modified Cam-Clay model (MCC) for the elasto-plastic behavior and Hershel-Bulkley rheological model (HB) for the viscous behavior. The second-order work criterion has been used to describe the solid-fluid transition. The model was applied to mudflows affecting the Vaches Noires cliffs (Normandy, France).
