Review and Recent Developments on the Perfectly Matched Layer (PML) Method for the Numerical Modeling and Simulation of Elastic Wave Propagation in Unbounded Domains
Florent Pled, Christophe Desceliers
This review article revisits and outlines the perfectly matched layer (PML) method and its various formulations developed over the past 25 years for the numerical modeling and simu…
Symmetry classes in piezoelectricity from second-order symmetries
Marc Olive, Nicolas Auffray
The piezoelectricity law is a constitutive model that describes how mechanical andelectric fields are coupled within a material. In its linear formulation this law comprises threec…
Robust Multiscale Identification of Apparent Elastic Properties at Mesoscale for Random Heterogeneous Materials with Multiscale Field Measurements
Tianyu Zhang, Florent Pled, Christophe Desceliers
The aim of this work is to efficiently and robustly solve the statistical inverse problem related to the identification of the elastic properties at both macroscopic and mesoscopic…
On the isotropic moduli of 2D strain-gradient elasticity
Nicolas Auffray
In the present paper, the simplest model of strain-gradient elasticity will be considered, that is the isotropy in a bidimensional space. Paralleling the definition of the classic…
Analytical continuum mechanics à la Hamilton-Piola: least action principle for second gradient continua and capillary fluids
N. Auffray, F. dell'Isola, V. Eremeyev +2
In this paper a stationary action principle is proven to hold for capillary fluids, i.e. fluids for which the deformation energy has the form suggested, starting from molecular arg…
A discrete element study of settlement in vibrated granular layers: role of contact loss and acceleration
Ali Karrech, Denis Duhamel, Guy Bonnet +4
This paper deals with the vibration of granular materials due to cyclic external excitation. It highlights the effect of the acceleration on the settlement speed and proves the exi…
