An ultrasonic measurement of stress in steel without calibration: the angled shear wave identity
Guo-Yang Li, Artur Lewis Gower, Michel Destrade
Measuring stress levels in loaded structures is crucial to assess and monitor their health, and to predict the length of their remaining structural life. However, measuring stress…
Surface waves and surface stability for a pre-stretched, unconstrained, non-linearly elastic half-space
J. G. Murphy, M. Destrade
An unconstrained, non-linearly elastic, semi-infinite solid is maintained in a state of large static plane strain. A power-law relation between the pre-stretches is assumed and it…
Large-amplitude Love waves
Elizabete Rodrigues Ferreira, Philippe Boulanger, Michel Destrade
In the context of the finite elasticity theory, we consider a model for compressible solids called 'compressible neo-Hookean material'. We show how finite-amplitude inhomogeneous p…
Asymptotic results for bifurcations in pure bending of rubber blocks
Ciprian Coman, Michel Destrade
The bifurcation of an incompressible neo-Hookean thick block with a ratio of thickness to length {eta}, subject to pure bending, is considered. The two incremental equilibrium equa…
A wave near the edge of a circular disk
Michel Destrade, Yibin Fu
It is shown that in the Love-Kirchhoff plate theory, an edge wave can travel in a circular thin disk made of an isotropic elastic material. This disk edge wave turns out to be fast…
Piezoacoustic wave spectra using improved surface impedance matrix: Application to high impedance-contrast layered plates
Victor Y. Zhang, Bertrand Dubus, Bernard Collet +1
Starting from the general modal solutions for a homogeneous layer of arbitrary material and crystalline symmetry, a matrix formalism is developed to establish the semi analytical e…
