This paper explores flood-induced hydrodynamic and debris impact forces on masonry arch bridges using the numerical method smoothed particle hydrodynamics (SPH). Masonry make up a significant proportion of bridge stock in many parts world, including UK US. Although is durable form, those spanning watercourses can be vulnerable to effects flooding. Where fast flood flows impinge superstructure, ...

This paper describes a novel hybrid method for fluid simulation of saturating anisotropic porous material via fluid-structure coupling. Our framework employs particle finite element method (PFEM) that not only adopts Lagrangian scheme to model the motion of freely-moving particles, but also produces the extended Delaunay Tessellation to furnish the governing equations with FEM discretization. W...

Particle finite element method (PFEM) is an effective numerical tool for solving large-deformation problems in geomechanics. By incorporating the node integration technique with strain smoothing into PFEM, we proposed smoothed particle (SPFEM). This paper extends SPFEM to three-dimensional cases and presents a executed on graphics processing units (GPUs) boost computational efficiency. The deta...

This study proposes a generalized coordinate smoothed particle hydrodynamics (GCSPH) method coupled with an overset using the total Lagrangian formulation for solving large deformation and crack propagation problems. In GCSPH, physical space is decomposed into multiple domains, each of which mapped to avoid singularities as well flexibly change spatial resolution. The SPH particles are then non...

We propose a particle-based method to simulate thin-film fluid that jointly facilitates aggressive surface deformation and vigorous tangential flows. build our dynamics model from the tension driven Navier-Stokes equation with dimensionality reduced using asymptotic lubrication theory customize set of differential operators based on weakly compressible Smoothed Particle Hydrodynamics (SPH) for ...
