Numerical Study of Quasi-Static to Dynamic Pullout Capacity of Anchors in Sand
In this study, a particle-based continuum numerical approach based on the smoothed particle hydrodynamics (SPH) method coupled with the finite element method (FEM) has been developed to investigate the failure mechanism and ultimate pullout capacity of soil anchors from quasi-static to dynamic conditions. The results of this study suggest that the ultimate pullout resistance depends on the failure mechanism of the mobilized soil. It was found that the failure mechanism and soil deformation depend on the anchor embedment depth and are rate dependent. Anchors embedded at deeper depths are shown to be more influenced by pullout velocities than those embedded at shallower depths. The failure shape depends on the anchor pullout velocity in addition to the soil density and embedment depth.
