Abstract
The article shows Generalized Interpolation Material Point Method numerical simulation of the Sainte Monique landslide. The simulation uses a strain-rate dependent Tresca constitutive model, extended with strain softening behaviour for structured clays. First, the paper replicates fall cone tests to validate the constitutive model and to select the material parameters. Afterwards, the paper shows the Sainte Monique landslide simulation which additionally considers shear band thickness to reduce the mesh-dependence. The results suggest that the strain-rate affects the prediction of the run-out distances and leads to the landslide acceleration-deceleration cycles (reported in, e.g. Corominas et al., 2005; Wang et al., 2010).
