It has been 25 years since Sulsky and her coworkers developed the first version of the
material point method (MPM): a quasi particle method to solve continuum mechanics …

Many problems in geotechnical engineering involve large movements or rotations,
examples include natural processes such as landslides, and man-made processes such as …

A new algorithm is developed to improve the accuracy and efficiency of the material point
method for problems involving extremely large tensile deformations and rotations. In the …

We propose and numerically implement a constitutive framework for granular media that
allows the material to traverse through its many common phases during the flow process …

The material point method (MPM) has demonstrated itself as a computationally effective
particle method for solving solid mechanics problems involving large deformations and/or …

A new algorithm is described which extends the material point method (MPM) to allow
explicit cracks within the model material. Conventional MPM enforces velocity and …

Advances in numerical methods have provided useful tools for investigating the complex
behaviour of landslides, which can be a valuable support for landslide hazard assessment …

Quasistatic and implicit time integration schemes are typically employed to alleviate the
stringent time step restrictions imposed by their explicit counterparts. However, both …

Large deformation in soils and frictional soil-structure contact are important geotechnical
processes that should be considered when designing protective structures to cushion the …

An implicit material point method (MPM), a variant of the finite element method (FEM), is
presented in this paper. The key feature of MPM is that the spatial discretisation uses a set of …
