Reciprocity in Elastodynamics
TL;DR: In this article, the authors present a novel method to solve for wave fields, shedding new light on the use of reciprocity relations for dynamic fields in an elastic body, which is relevant to several fields in engineering and applied physics such as medical imaging and non-destructive evaluation, acoustic microscopy, seismology, exploratory geophysics, structural acoustics, and the determination of material properties by ultrasonic techniques.

Quantitative assessment of through-thickness crack size based on Lamb wave scattering in aluminium plates
TL;DR: In this paper, the interaction of Lamb wave modes at varying frequencies with a through-thickness crack of different lengths in aluminium plates was analyzed in terms of finite element method and experimental study.
Journal ArticleDOI
A system model for the ultrasonic inspection of smooth planar cracks
TL;DR: In this paper, a system model for the ultrasonic inspection of smooth planar cracks in ferritic steel, using pulse-echo probes, is described, which is applied to problems of procedure design, assessment, and technical justification on power station plant.

Scattering of elastic waves in a perturbed isotropic half space with a free boundary. The limiting absorption principle
TL;DR: In this paper, the authors considered the self-adjoint operator governing the propagation of elastic waves in a perturbed isotropic half space with a free boundary condition and proved the limiting absorption principle in appropriate Hilbert spaces for this operator.

Modelling the propagation and scattering of elastic waves in inhomogeneous anisotropic media
TL;DR: In this paper, a finite-difference numerical model for studying the propagation and scattering of elastic waves in three-dimensional inhomogeneous and anisotropic media of arbitrary symmetry is presented.
