摘要：

We demonstrate that the multi-linear interpolation functions used on an Eulerian grid in standard MPM generate volumetric locking, which dominates the solution as bulk compressibility approaches the incompressible limit. We propose a simple relaxation procedure based on a three-field Hu-Washizu principle and demonstrate its applicability to modeling of granular flow problems.
