The material point method is an increasingly popular method for tackling solid mechanics problems involving large deformations. However, there are issues associated with applying boundary conditions in the method and, to date, no general approach for...

Overcoming volumetric locking in material point methods (2018)
Journal Article
Coombs, W., Charlton, T., Cortis, M., & Augarde, C. (2018). Overcoming volumetric locking in material point methods. Computer Methods in Applied Mechanics and Engineering, 333, 1-21. https://doi.org/10.1016/j.cma.2018.01.010

Material point methods suffer from volumetric locking when modelling near incompressible materials due to the combination of a low-order computational mesh and large numbers of material points per element. Large numbers of material points per element... Read More about Overcoming volumetric locking in material point methods.
