A nonlocal material point method for the simulation of large deformation problems in brittle soils
article
This paper investigates the implementation of a nonlocal regularisation of the material point method to
mitigate mesh-dependency issues for the simulation of large deformation problems in brittle soils. The adopted
constitutive description corresponds to a simple elastoplastic model with nonlinear strain softening. A number
of benchmark simulations, assuming static and dynamic conditions, were performed to show the importance
of regularisation, as well as to assess the performance and robustness of the implemented nonlocal approach.
The relevance of addressing stress oscillation issues, due to material points crossing element boundaries,
is also demonstrated. The obtained results provide relevant insights into brittle materials undergoing large
deformations within the MPM framework.
