Abstract Structural Health Monitoring (SHM) systems provide a useful tool to diagnose any
engineered structural system and eventual critical damage that may occur at any moment …

The growing use of composite materials for aerospace applications has resulted in the need
for quantitative methods to analyze composite components. Ultrasonic guided waves …

Compared to the traditional integer order viscoelastic model, a fractional order derivative
viscoelastic model is shown to be more accurate. A thorough knowledge of the dispersive …

In this paper an application of Artificial Neural Networks and Probability Ellipse methods for
damage detection using Lamb waves is presented. The wave propagation data are used to …

In this paper, an approach is presented to model the propagation of elastic waves and their
interaction with defects in plate structures. The formulation is based on the Scaled Boundary …

This work proposes a vibration-based damage detection approach for axially loaded beam-
type structures. The potential of the adopted approach is shown with an application to …

The traditional delay-and-sum imaging algorithm usually requires sending an excitation
pulse at each piezoceramic transducer and obtains a damage image by drawing only …

An algorithm to detect damage size and shape using a lead zirconate titanate (PZT)
transducer array for a plate structure is developed in this paper. During the process of …

Structural health monitoring (SHM) based on guided waves allows assessing the health of a
structure due to the sensitivity to the occurrence of delamination. However, wave …

In this paper, a numerical approach for the computation of dispersion relations for three-
dimensional waveguides with arbitrary cross-section is proposed. The formulation is based …
