A novel approach for nonlinear ultrasonics is presented which relies on an amplitude modulated high-frequency excitation, as distinct from the conventional vibro-acoustic approach based on a low-frequency pumping wave in combination with a high-frequ

Guided waves provide an attractive way to inspect plate-like structures due to their ability to propagate over long distances and their sensitivity to various types of defects. In this work, the disbond growth between an aluminium plate and a stiffen

The in situ monitoring of stresses provides a crucial input for residual life prognosis and is an integral part of structural health monitoring systems. Stress monitoring is generally achieved by utilising the acoustoelastic effect, which relates the

Wave mixing offers several practical benefits relative to harmonic generation for detecting both distributed and localised damage. An analytical model is proposed for predicting the frequency, mode and direction of propagation of the mixed modes aris

The nonlinear scattering of a longitudinal wave induced by the clapping of a pair of rough surfaces under a compressive pre-stress is investigated using a model that combines nonlinear springs and unilateral contact. This novel approach captures both

This paper presents a theoretical and finite element (FE) investigation of the scattering characteristics of the fundamental anti-symmetric (A0) Lamb wave at delaminations in a quasi-isotropic (QI) composite laminate. Analytical models based on the M

A consideration of the relevant length scales and time scales suggests that Mindlin plate theory provides a judicious model for damage detection. A systematic investigation of this theory is presented that emphasizes its mixed vector-scalar character

This paper presents an analytical approach using higher order plate theories to determine wave reflections from and transmissions through a damaged region in a beam. The damaged region is either treated as two split beams or as an inhomogeneity. The

A plate containing a circular hole, and reinforced by a patch may as a first approximation, be analysed by treating the reinforced structure as a plate containing an inclusion. This leads to a state of uniform stress in the inclusion. In this paper,

This paper presents a critical assessment of three analytical methods in determining the crack-tip plastic deformation under large scale and gross-section yielding conditions. These theoretical approaches include two stress-based cohesive zone models
