Pre-stressed bolted joints are widely used in civil structures and industries. The tightening
force of a bolt is crucial to the reliability of the joint connection. Loosening or over-tightening …

We present an overview of research developments related to the nonlinear vibroacoustic
modulation technique used for structural damage detection. The method of interest is based …

Abstract In recent years, Vibro-Acoustic Modulation (VAM) techniques for structural health
monitoring have received increasing attention. For such techniques, the sidebands and …

In this paper, a new type of non-pneumatic tire is designed. The pneumatic parts of standard
pneumatic tire are replaced by gradient anti-tetrachiral structure. Firstly, the in-plane …

A wave energy dissipation (WED)-based linear acoustic approach and a vibro-acoustic
modulation (VM)-based nonlinear method were developed comparatively, for detecting bolt …

Combined harmonics at sum-or difference-frequencies can be generated by the cross-
interactions of guided wave mixing in tested samples with material nonlinearity. However, it …

In order to pursue better crashworthiness and higher energy absorption efficiency, a new
type of multi-cell honeycomb (quadri-arc) was designed and followed by a series of …

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 …

Structural Health Monitoring (SHM) is the process of collecting, interpreting, and analysing
data from structures in order to determine its health status and the remaining life span …

The paper deals with the application of nonlinear vibro‐acoustic modulation technique for
detection and localization of impact damage in a laminated composite plate. An imaging …
