A high-strength bolt connection is the key component of large-scale steel structures. Bolt
loosening and preload loss during operation can reduce the load-carrying capacity, safety …

Laminate composites are commonly used for the production of critical mechanical structures
and components such as wind turbine blades, helicopter rotors, unmanned aerial vehicle …

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

The magnifying effect of resonance vibration on vibro-acoustic modulation (VAM) is
important for the study of nonlinear ultrasonic behaviors and yet to be completely …

The goal of this article is to provide a review of the experimental techniques and procedures
using vibration methods for the Structural Health Monitoring (SHM) of Polymer-Matrix …

Linear ultrasonics methods based on the principle of reflection, transmission, dissipation of
sound waves have been traditionally used to detect delaminations in composite structures …

The occurrence of matrix cracks, fibre failures and delaminations results in a critical
degradation of the structural integrity of composites. A reliable early detection of these …

Contact-type defects are prevalent in composite constructions and sandwich panels due to
failure mechanisms such as bolt loosening and delamination. Contact acoustic nonlinearity …

Nonlinear wave modulation (NWM) is a promising technique for structural health monitoring
and contact-type damage detection. In NWM, the severity of the damage is proportional to …

This paper investigates the utility of physics-informed machine learning models for vibro-
acoustic modulation (VAM)–based damage localization in concrete structures. Vibro …
