Comparison of UBCSAND and Hypoplastic soil model predictions using the Material Point Method

Liquefaction effects predicted by implementing two well-known constitutive models for sandy soils are compared; i.e., the Hypoplastic soil model (HPS) and the UBCSAND model. To numerically simulate dynamic loading, the Convected Particle Domain Interpolation (CPDI) method, an advanced Material Point Method (MPM), is employed within a multi-phase framework. The numerical results from the UBCSAND model are compared against published experimental …
