Proceedings ArticleDOI
Characterization of Lamb waves in absorbing plates
TL;DR: In this article, the authors used a combination of laser ultrasonics, signal processing and analytical modeling techniques to examine the propagation of transient Lamb waves in absorbing plates, in particular an isotropic plate with a lossless fluid on one side.
Proceedings ArticleDOI
Reflection and diffraction corrections for nonlinear materials characterization by quasi-static pulse measurement
TL;DR: In this paper, analytical and numerical simulation results are presented to illustrate two types of finite-size effects, namely, the finite axial dimension of the specimen cannot be simply accounted for by a linear reflection coefficient that neglects the nonlinear interaction between the combined incident and reflected fields.
Proceedings ArticleDOI
Feasibility of using nonlinear guided waves to measure acoustic nonlinearity of aluminum
TL;DR: In this paper, the feasibility of measuring acoustic nonlinearity in aluminum with different ultrasonic guided wave modes was investigated, and experimental results using Rayleigh and Lamb-based wave modes were presented, and a comparison of the efficiency of these modes to measure acoustic impedance was given.
Journal ArticleDOI
Transfer functions to remove the effect of corners on Rayleigh waves
TL;DR: In this paper, the authors used laser ultrasonic techniques to develop transfer functions that remove the effect of geometric features on experimentally measured Rayleigh waves using a repeatable, broadband optical source and a high-fidelity sensor.
A Multi-Scale Structural Health Monitoring Approach for Damage Detection, Diagnosis and Prognosis in Aerospace Structures
TL;DR: In this paper, a multi-scale finite element method was developed to bridge a fine-scale mesh around a defect and a coarse-scale di scretization of the entire domain, and was validated by comparing scattering of guided waves from damage in a plate with analytical and numerical solutions.
