Ultrasonic guided wave inspection is expanding rapidly to many different areas of manufacturing and in-service inspection. The purpose of this paper is to provide a vision of ultrasonic guided wave inspection potential aswe move forward into the new millennium. An increased understanding of the basic physics and wave mechanics associated with guided wave inspection has led to an increase in practical nondestructive evaluation and inspection problems. Some fundamental concepts and a number of different applications that are currently being considered will be presented in the paper along with a brief description of the sensor and software technology that will make ultrasonic guided wave inspection commonplace in the next century.read more

Characterisation of guided wave dispersion in isotropic tubes based on damping finite element boundaries
Zijian Wang,Binkai Shi,Chen Fang +2 more
TL;DR: In this article , damping boundaries are developed as a set of finite element (FE) frames with gradually increasing damping coefficients to alleviate boundary reflections, and wave signals are simulated through the FE model with the damping boundary only contain the waves from the transmitter to the receiver, without the interferences of the boundary reflections.
Damage detection of defects using linear and nonlinear guided waves
TL;DR: In this article, an advanced 3D explicit finite element model for predicting the interaction of nonlinear guided wave with defects in structures from both numerical and experimental prospective is proposed. But, the model is not suitable for the case of anisotropic materials, such as aluminum and steel.

A challenging and promising effort toward QNDE for inaccessible and invisible defects; nonlinear guided wave NDE
Weibin Li,Younho Cho +1 more
TL;DR: The use of ultrasonic guided wave, which has been widely accepted as a conventional, screening NDE tool to overcome the inaccessibility of large scale structural integrities is now being extended to early stage damage detection in conjunction with its nonlinear features for more precise material characterization as mentioned in this paper.

Directivity of quasi-SH0 modes in cubic anisotropic media.
TL;DR: In this paper , the authors studied the zeroth order shear horizontal modes and the quasi-SH0 modes in cubic-anisotropic plates and proposed a formula to describe the scattering directivity of these guided wave modes in arbitrary directions.

Ultrasonic Waves in Solid Media
TL;DR: In this article, the theory of elasticity was introduced and basic formulas and concepts in complex variables in the theory and application of wave propagation were discussed. But the authors did not consider the effects of wave scattering on the wave propagation experiments.
