【 摘 要 】

The effective stress model is used to model the stress-strain, volumetric, and strength behavior in saturated materials under shock loading. The effective stress concept provides a predictive model of the behavior of wet porous materials based on the dry material properties. An effective stress model that allows for arbitrary fluid and solid equations of state and varying levels of saturation is incorporated into an adaptive mesh refinement (AMR) Eulerian shock physics hydrocode. Good agreement is found between simulation results and experimental data for saturated materials, even at moderately high pressures.
