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…
