Linear-frictional contact model for 3D discrete element simulations of granular systems
Matthew R. Kuhn, Kiichi Suzuki, Ali Daouadji
The linear-frictional contact model is the most commonly used contact mechanism for discrete element (DEM) simulations of granular materials. Linear springs with a frictional slide…
Relaxed micromorphic broadband scattering for finite-size meta-structures -- a detailed development
Alexios Aivaliotis, Domenico Tallarico, Marco-Valerio D'Agostino +3
The conception of new metamaterials showing unorthodox behaviors with respect to elastic wavepropagation has become possible in recent years thanks to powerful dynamical homogeniza…
Low-and high-frequency Stoneley waves, reflection and transmission at a Cauchy/relaxed micromorphic interface
Alexios Aivaliotis, Ali Daouadji, Gabriele Barbagallo +3
In this paper we study the reflective properties of a 2D interface separating a homogeneous solid from a band-gap metamaterial by modeling it as an interface between a classical Ca…
Stiffness pathologies in discrete granular systems: bifurcation, neutral equilibrium, and instability in the presence of kinematic constraints
Matthew R. Kuhn, Florent Prunier, Ali Daouadji
The paper develops the stiffness relationship between the movements and forces among a system of discrete interacting grains. The approach is similar to that used in structural ana…
Multi-directional behavior of granular materials and its relation to incremental elasto-plasticity
Matthew R. Kuhn, Ali Daouadji
The complex incremental behavior of granular materials is explored with multi-directional loading probes. An advanced discrete element model (DEM) was used to examine the reversibl…
Quasi-static incremental behavior of granular materials: elastic-plastic coupling and micro-scale dissipation
Matthew R. Kuhn, Ali Daouadji
The paper addresses a common assumption of elastoplastic modeling: that the recoverable, elastic strain increment is unaffected by alterations of the elastic moduli that accompany…
