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...

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...

Open AccessMultiphase lattice Boltzmann simulations for porous media applications
Over the last two decades, lattice Boltzmann methods have become an increasingly popular tool to compute the flow in complex geometries such as porous media. In addition to single phase simulations allowing, f...

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...
