This paper presents a method within the family of the discrete element method (DEM) capable of accurately capturing grain shape by using Non-Uniform Rational Basis-Splines (NURBS). The new method, called GEM, bypasses one of the current bottlenecks i

A new rate-dependent plasticity model for dilative granular media is presented, aiming to bridge the seemingly disparate solid- and fluid-like behavioral regimes. Up to date, solid-like behavior is typically tackled with rate-independent plasticity m

In this paper we report some key advances in the characterization and modelling of granular matter. Recent developments on experimental and imaging techniques (X-ray CT, 3D-DIC) are allowing modellers to leverage the rich information encoded at subsc

We present a new method capable of inferring, for the first time, inter-particle contact forces in irregularly-shaped natural granular materials (e.g., sands), using basic Newtonian mechanics and balance of linear momentum at the particle level. The

Granular sands are characterized and modeled here by explicitly exploiting the discrete-continuum duality of granular matter. Grain-scale kinematics, obtained by shearing a sample under triaxial compression, are coupled with a recently proposed multi

We will present a novel technique for bridging the micro- and macro- mechanical scales in granular materials. In particular, we will show that a hierarchical multiscale technique can be coupled with advanced experiments to predict the behavior of san

This paper briefly describes a hierarchical multiscale method used to model the behavior of granular matter by linking the fundamental granular scale with the continuum scale, which is being modeled using frictional elasto-plasticity. We show a parti
