Coupled peridynamics and scaled boundary finite element method for the dynamic fracture problem on polygonal meshes

To address two critical bottlenecks in peridynamics (PD), namely its strong dependence on uniform discretization and the difficulty in boundary condition implementation, this study proposes a novel Peri-PolySBFEM framework. The framework achieves its advances through three key innovations. First, polygonal meshes are...

Erosion-driven earth dam failure: A two-phase multi-state smoothed particle hydrodynamics model

Earth dam failures are typically triggered by overtopping, involving complex soil–water interactions and progressive structural collapse. Empirical and semi-empirical models provide efficient estimates of breach parameters and outflow hydrographs, but they usually offer limited resolution of the local stress state, rhe...
