Abstract

In this research, a rate-dependent solid constitutive model capable of modeling granular flow behavior was employed with the smoothed particle hydrodynamics method (SPH). In comparison with the conventional methods using SPH in the framework of computational fluid dynamics, SPH method used in this study was simple and accurate. The developed model was verified with well documented experimental data of dry granular flume tests, and flow pattern and impact forces on rigid wall were investigated. The results of this study show the effects of inclination angle, initial soil deposition shape, and the distance between the flow origin and obstacle on the peak and residual force of the granular flow.
