Fatigue damage is difficult to detect and evaluate non-destructively, specifically at its early
stages (before the macro-crack formation). In this study, fatigue damage is evaluated based …

This paper presents a delamination damage detection technique based on the nonlinear
response of Lamb waves in composite laminates. In the approach, a network of transducers …

Nonlinear guided wave has been recognized as a potential means to characterize the state
of material microstructures in solids. However, nonlinear guided wave approaches based on …

Abstract Evaluation of fatigue damage using nonlinear guided wave mixing has been
studied extensively over the past decade. It was found that the combinational harmonics as …

Many engineering structural elements make use of adhesively bonded joints due to its
lighter weight, load distribution and transmission mechanisms. The safety of the structure …

Bolted joints are fundamental to numerous structural components in engineering practice.
Nevertheless, their failure or even their loosening can lead to insufficient performance and …

It is crucial to detect and evaluate early material degradation caused by micro-cracks in key
engineering structures. This paper investigates the resonant behavior of one-way Lamb …

A nonlinear ultrasonic method is proposed based on a group of newly discovered wave
triplets where two primary codirectional shear-horizontal SH0 waves mix in a weakly …
