Simulating Earthquake-triggered Runout using Higher-order Hydromechanical MPM and PM4Sand
… table loading and free-field modes. Finally, the PM4Sand constitutive model is implemented in the hydromechanical MPM to enable the model to capture the cyclic behavior of sand, including liquefaction triggering and cyclic mobility. Verification and validation of the framework are performed by …

Estimating the effectiveness of stone columns in mitigating post-liquefaction settlement using Plaxis 2D
… Method (FEM) and constitutive relationship, PM4Sand model, as it has been extended to account for reconsolidation settlement. The ability of the numerical framework to capture reconsolidation settlement is validated by replicating a shake table test performed on Ottawa F-55 sand. Results are …

One-dimensional site response analyses in potentially liquefiable soil profiles
… (CES) in New Zealand were used to validate the PM4Sand constitutive model. Soil profile characterization was key to accurate prediction of excess pore pressure response and accounting for any densification during the CES. Response during multiple earthquakes was captured effectively and …

Performance of Columnar Reinforced Ground during Seismic Excitation
… Dafalias-Manzari, Plasticity Model for Sands (PM4Sand) and Pressure-Dependent-Multi-Yield-02 (PDMY02) model. They were employed to predict behavior of soils with different relative densities and under different confining pressures during monotonic and cyclic loading. PDMY02 was identified as …
