Problems involving large deformations are the focus of numerical modeling researches in recent decades due to the challenge of finding a kinematic appropriate description of the continuum. In recent years, different formulations have been used to describe such problems as the Arbitrary Lagrangian Eulerian (ALE) method and the Material Point Method (MPM). These two methods allow to perform dynamic analyzes involving large deformations. In this way, this work aims to present a comparison of problems applied to Geotechnics involving large deformations and large displacements, using MPM and FEM associated with the ALE method. For this purpose, three problems are simulated: sliding of blocks on an inclined plane, runout process of sand and instability of a slope using the MPM and the FEM associated with the ALE method. In all cases a comparison of the results is presented, and the advantages and disadvantages of each method are discussed.

“…It was applied to the modelling of anchors placed in soil [8], to excavator bucket filling [9], to problems of granular flow in a silo [10], to the simulation of experiments related to fault induced ground deformations [11], to run-out analysis of earthquakeinduced soil flows [12] and to geomembrane response to settlement in landfills [13]. Also, a quasi-static version of MPM has been developed for large deformations in geomechanics [14].…”

Abstract. Seismic safety of earth or rockfill dams and embankments is strongly conditioned by permanent displacements caused by earthquakes. For a severe earthquake, the permanent displacement pattern results from the combination of displacements generated by volumetric and shear plastic strains distributed within the structure, and those caused by sliding of the soil mass along one or more failure surfaces. Numerical procedures commonly used in practice do not consider the strain localization phenomena at failure surfaces and the associated mesh dependence of the solution. Typically, nonlinear finite element or finite difference codes yield an estimate of distributed deformations and dynamic response, without accounting for the plastic strain localization problem. In addition, some of the numerical approaches used in practice do not consider the change of configuration caused by large displacements. The material point method or MPM is a lagrangian "particle-mesh" numerical method. It has been previously used in modeling dynamic problems with large displacements and strain localization. With MPM, a body is discretized into a collection of lagrangian particles, which carry all the data needed to define the body's state. Interaction between particles takes place in a background fixed mesh, similar to those used in the finite element method. The MPM is applied in this paper to model the three dimensional dynamic response of Punta Negra dam, a concrete faced gravel dam which is being built in San Juan Province, Argentina..

“…Significant research has focused on applications of this type (e.g., [11,12,17,34,59,61,40]), but much work has also been done in additional areas-pushing the capabilities of the MPM and exploring new applications. These include applications in geotechnical engineering [3,60,66], fracture and material failure [15,19,20,41,44,45,53,55], contact, material interaction, and penetration [6,7,23,24,27,33,38,46,42,64,65], as well as general implementation considerations [5,25,28,29,36,48,50].…”
