The material point method (MPM) has been gaining increasing popularity as an appropriate approach to the solution of coupled hydro-mechanical problems involving large deformation. In this paper, we survey current state-of-the-art in MPM simulation behaviour two-phase porous geomaterials. review covers recent advances and development their extensions capture deformations. focus is aiming at providing a clear picture what or not developed implemented for simulating deformation problems, which will provide some direct reference both practitioners researchers.

Abstract Climate warming accelerates permafrost thawing, causing warming‐driven disasters like ground collapse and retrogressive thaw slump (RTS). These phenomena, involving intricate multiphysics interactions, phase transitions, nonlinear mechanical responses, fluid‐like deformations, pose increasing risks to geo‐infrastructures in cold regions. This study develops a thermo‐hydro‐mechanical (THM) coupled single‐point three‐phase material point method (MPM) simulate the time‐dependent transition large deformation behavior arising from thawing or freezing of ice/water porous media. The mathematical framework is established based on multiphase mixture theory which ice treated as solid constituent playing role skeleton together with soil grains. additional strength due cementation characterized via an saturation‐dependent Mohr–Coulomb model. formulations are solved using fractional‐step‐based semi‐implicit integration algorithm, can offer both satisfactory numerical stability computational efficiency when dealing nearly incompressible fluids extremely low permeability conditions frozen Two hydro‐thermal coupling cases, that is, inclusion Talik closure/opening, first benchmarked show correctly conduction‐ convection‐dominated thermal regimes systems. fully THM responses further validated by simulating 1D consolidation 2D rock example. Good agreements experimental results achieved, impact variations including settlement frost heave, successfully captured. Finally, predictive capability MPM thawing‐triggered failure demonstrated modeling RTS strip footing ground.
