Solid–liquid coupled material point method for simulation of ground collapse with fluidization
Y Yamaguchi, S Takase, S Moriguchi… - Computational Particle …, 2020 - Springer
An improved version of the solid–liquid coupled material point method (MPM) is proposed to
simulate ground collapses with fluidization involving transition processes from soil structures
to flowing mixture. A water-saturated soil is assumed based on porous media theory, and the
physical quantities of the soil and water phases are assigned to two separate sets of
particles (material points). The main contribution of this study is the introduction of the
fractional step projection method for the time discretization of the momentum equation of the …
