Evaluation of effective wave velocities in polycrystalline materials using the ultrasonic reflection matrix
Gatien Clément, Alexandre Aubry, Cécile Brütt +2
In-depth characterization of heterogeneous materials has long been a challenge in non-destructive testing. Here, a method is proposed to determine the elastic constants of metallic…
Weight of single and recurrent scattering in the reflection matrix of complex media
Cécile Brütt, Alexandre Aubry, Benoît Gérardin +2
In a heterogeneous medium, the wavefield can be decomposed as an infinite series known as the Born expansion. Each term of the Born expansion corresponds to a scattering order, it…
Negative refraction of Lamb modes: A theoretical study
François Legrand, Benoît Gérardin, Jérôme Laurent +2
This paper provides a theoretical investigation of negative refraction and focusing of elastic guided waves in a free-standing plate with a step-like thickness change. Under certai…
