Localized modes in imperfect periodic structures

Lack of periodicity in engineering structures can arise because of imperfections in the production process or a particular purpose to produce desirable physical effects. This contribution presents an approach to characterize the influence of the…

Numerical Investigation of Ultrasonic Scattering Phenomena at the Grain-Scale in Polycrystalline Materials

In polycrystalline materials, elastic waves strongly interact with grain boundaries and their propagation generates complex ultrasonic scattering phenomena. The recorded signals are generally difficult to interpret but contain rich information…

Participation au développement d’un aimant haut champ 30T en REBaCuO

Superconductors are divided into two categories, low critical temperature superconductors (LTS) and high critical temperature superconductors (HTS). With LTS, strict limitations are imposed on the operating temperature (

LICORNE a benchmark on numerical method for non-linear site response analysis involving pore water pressure

Following the benchmark PRENOLIN for 1D non-linear site response analysis a new benchmark is proposed to assess the effect of both, the pore water pressure generation and the liquefaction occurrence. For now, 11 teams, mainly from French institutes,…

Effective rationality of second order symmetric tensor spaces

We consider the natural SO(3, k) linear representation, k = C or R, on the k vector space V = nS2(R3) of n second order symmetric tensors, the associated invariant field k(V)SO(3,k) being known to be a purely transcendental extension in the complex…

An improved continuous damage model to estimate multiaxial fatigue life under strain control problems

In this contribution, a modification and application of the Lemaitre damage evolution law is proposed for the problem of fatigue life estimate under low number of cycles. For this, the denominator of damage, considered constant for Lemaitre, was…

A generic topography reconstruction method based on multi-detector back scattered electron images

Surface topographies can be reconstructed from backscattered electron (BSE) images captured from different detector orientations. This article presents a very general approach to this problem, in the spirit of photometric stereo methods, allowing…

A Nanomechanical Testing Framework Yielding Front&Rear-Sided, High-Resolution, Microstructure-Correlated SEM-DIC Strain Fields

Abstract Background The continuous development of new multiphase alloys with improved mechanical properties requires quantitative microstructure-resolved observation of the nanoscale deformation mechanisms at, e.g., multiphase interfaces. This calls…
