Failure in geomaterials: continuous and discrete analyses
TL;DR: In this paper, the authors considered Hill's condition of stability and diffuse modes of failure in geomaterials in a dual framework: continuum mechanics and discrete mechanics, and concluded that the second order work criterion (under its dual form: continuous and discrete) can be a proper tool to analyse diffuse mode of failure.
Journal ArticleDOI
Bifurcation and second-order work in geomaterials
TL;DR: In this article, the ability of a material rate-independent system to evolve toward another mechanical state from an equilibrium configuration, with no change in the control parameters, is investigated, and the existence of both conjugate incremental strain and stress such that the second-order work vanishes is established as a necessary and sufficient condition for the appearance of bifurcation.
Journal ArticleDOI
Diffuse failure in geomaterials: Experiments and modelling
TL;DR: In this article, the authors considered undrained triaxial loading on very loose sands and the failure mode occurring at q-peak, and, in a second part, the bifurcation domain of sands in plane strain conditions through strain proportional paths and incrementally piecewise linear and non-linear constitutive relations.
Journal ArticleDOI
Hydro-mechanical modelling of landslides with a material instability criterion
TL;DR: In this article, the Lagamine finite element code was used to analyze the Petacciato and Trevoux landslides in the Adriatic coast of Italy and France, respectively.
