DOI: 10.1016/j.jmps.2019.103690
Abstract: Abstract Flow-induced failure of granular materials is relevant to a broad range of geomechanical applications. Plasticity, which is the inherent failure mechanism of most granular materials, enables large deformations that can invalidate linearised models. Motivated… read more here.
