Effect of particle shape on the strength and deformation mechanisms of ellipse‐shaped granular assemblages
John M. Ting, Larry Meachum, Jeffrey D. RowellThis paper presents the results of a Discrete Element Method study on the influence of particle shape on the strength and deformation behaviour of two dimensional assemblages of…
Visualization of dynamic fluid simulations: waves, splashing, vorticity, boundaries, buoyancy
Nick Foster, Dimitri MetaxasA software package is developed for the modelling and animation of viscous incompressible fluids. The full time‐dependent Navier‐Stokes equations are used to simulate 2D and 3D…
Numerical validation of a constitutive theory for an arbitrarily fractured solid
B.C. Trent, L.G. MargolinWe have developed a general constitutive theory that estimates the effective elastic moduli of a cemented granular material by applying statistical mechanical averaging to a…
A method to resolve ambiguities in corner‐corner interactions between polygons in the context of motion simulations
Jayaraman Krishnasamy, Mark J. JakielaThe motion of systems of polygonal objects is characterized by discontinuities due to changes in the set of contacts between polygons. Effective simulations of such a motion…
A combined finite‐discrete element method in transient dynamics of fracturing solids
A. Munjiza, D.R.J. Owen, N. BicanicThis paper discusses the issues involved in the development of combined finite/discrete element methods; both from a fundamental theoretical viewpoint and some related algorithmic…
A flexible boundary for three‐dimensional dem particle assemblies
Matthew R. KuhnAn algorithm is presented for creating a flexible boundary to analyse three‐dimensional assemblies of spheres. It can be used to study localization phenomena in particulate…
A linear complexity intersection algorithm for discrete element simulation of arbitrary geometries
J.R. Williams, R. O’ConnorWe present an algorithm for contact resolution that is valid for a wide variety of polygonal two dimensional shapes and is of linear computational complexity. The algorithm is…
