    Fracture shearing of polycrystalline material simulations using the material point method

    In this work, we present a newly developed workflow to study the combined effect of shear and normal stresses upon a preexisting fracture plane. This workflow is used to study the behavior of both single grain...

    Modeling damage and plasticity in aggregates with the material point method (MPM)

    In order to simulate the failure of aggregate materials, a coupled damage and plasticity model is used with the material point method (MPM). A pressure-dependent J2 plasticity law, the Drucker–Prager model, is...

    A strategy to couple the material point method (MPM) and smoothed particle hydrodynamics (SPH) computational techniques

    A strategy is introduced to allow coupling of the material point method (MPM) and smoothed particle hydrodynamics (SPH) for numerical simulations. This new strategy partitions the domain into SPH and MPM regio...

    Development of stress boundary conditions in smoothed particle hydrodynamics (SPH) for the modeling of solids deformation

    This paper develops a method for imposing stress boundary conditions in smoothed particle hydrodynamics (SPH) with and without the need for dummy particles. SPH has been used for simulating phenomena in a numb...

    Electromagnetic excitation of particle suspensions in hydraulic fractures using a coupled lattice Boltzmann-discrete element model

    This paper describes the development of a computational framework that can be used to describe the electromagnetic excitation of rigid, spherical particles in suspension. In this model the mechanical interacti...

    Characterizing flow in oil reservoir rock using SPH: absolute permeability

    In this paper, a three-dimensional smooth particle hydrodynamics (SPH) simulator for modeling grain scale fluid flow in porous rock is presented. The versatility of the SPH method has driven its use in increas...
