Abstract

The material point method (MPM) is a numerical tool able to model very large deformations in solid mechanics such as geotechnical problems. To date, soil-tool interaction modelling in the MPM is somewhat difficult, especially when the tool position is not stationary. Usually, the tool’s boundaries do not coincide with the MPM grid and therefore boundary conditions cannot be imposed directly on the grid nodes. An implicit approach based on a penalty type method to impose essential boundary conditions in the MPM has been developed and used in the paper to demonstrate how to model frictionless soil-tool interaction mechanism [3]. This approach assumes that the tool is a rigid body as the deformation of the tool boundaries are insignificant. The same approach can also be used to model the interaction between structures and soil such as foundations.
