Acoustic scattering characteristics of a thick-walled orthotropic cylindrical shell at oblique incidence.
TL;DR: The method of wave function expansion is adopted to study the scattering of a plane harmonic acoustic wave incident at an arbitrary angle upon an arbitrarily thick cylindrically orthotropic homogeneous cylindrical shell submerged in and filled with compressible ideal fluids.
Journal ArticleDOI
Experimental and theoretical study of acoustic waves generated by a laser line pulse in an optically absorptive isotropic cylinder.
TL;DR: Compared with an auxiliary simulation, which assumes the model of a dipole source located at the cylinder surface, the effect of optical penetration on the shape of the wave form and also on the relative amplitude of bulk and surface waves is revealed.

Measurement of the stiffness coefficients of a viscoelastic composite material with laser-generated and detected ultrasound
S. Guilbaud,B. Audoin +1 more
TL;DR: In this paper, a model for acoustic propagation in composites is developed to analyze the accuracy of the stiffness coefficients determined from the measured acoustic signals, which accurately predicts the focusing effects caused by anisotropy and the spreading of the signals caused by dispersion and attenuation.

Elastic constants determination of anisotropic materials from phase velocities of acoustic waves generated and detected by lasers
F. Reverdy,B. Audoin +1 more
TL;DR: It is shown that a judicious sum of signals obtained for various positions of the line source at the surface of a sample leads to the synthesis of an acoustic plane wave for which the odd phenomena disappear.
