THE MATERIAL POINT METHOD IN SOIL MECHANICS PROBLEMS

摘要

The material point method-the finite element method formulated in an arbitrary Lagrangian-Eulerian description of motion-is applied to large strain problems of soil mechanics. Two-dimensional, dynamic problems of pile driving (axisymmetry) and retaining wall failure (plane strain) are analysed. The case of non-cohesive models of the soil is analysed-the elastic-plastic and elastic-viscoplastic material models are applied.
