Finite element modeling of dynamic frictional rupture with rate and state friction
Roozbeh Rezakhani, Fabian Barras, Michael Brun +1
Numerous laboratory experiments have demonstrated the dependence of the friction coefficient on the interfacial slip rate and the contact history, a behavior generically called rat…
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…
Relaxed micromorphic model of transient wave propagation in anisotropic band-gap metastructures
Gabriele Barbagallo, Domenico Tallarico, Marco Valerio D'Agostino +3
In this paper, we show that the transient waveforms arising from several localised pulses in a micro-structured material can be reproduced by a corresponding generalised continuum…
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…
