Particle-to-surface frictional contact algorithm for material point method using weighted least squares

[Display omitted] This study presents a new particle-to-surface frictional contact algorithm for the material point method (MPM) to simulate the interaction between material points and rigid bodies. Although a grid-based multivelocity field technique is a common method that works well with MPM, ther...
