Investigation of the numerical simulation of debris flow fluid with concern of phase transition
From a variety of yield stress fluid models, an elastoviscoplastic Herschel-Bulkley (EVPHB) model written in 3D is selected and coupled with a Finite Element Method with Lagrangian Integration Points (FEMLIP) to solve boundary value problems with large deformation process.By tracing the historical variables of a material point, it is verified that
