Guided Waves in Structures for SHM 
The Time – domain Spectral Element Method

Understanding and analysing the complex phenomena related to
elastic wave propagation has been the subject of intense research
for many years and has enabled application in numerous fields of
technology, including structural health monitoring (SHM). In the
course of the rapid advancement of diagnostic methods utilising
elastic wave propagation, it has become clear that existing methods
of elastic wave modeling and analysis are not always very useful;
developing numerical methods aimed at modeling and analysing these
phenomena has become a necessity. Furthermore, any methods
developed need to be verified experimentally, which has become
achievable with the advancement of measurement methods utilising
laser vibrometry.

Guided Waves in Structures for SHM reports on the
simulation, analysis and experimental investigation related
propagation of elastic waves in isotropic or laminated structures.
The full spectrum of theoretical and practical issues associated
with propagation of elastic waves is presented and discussed in
this one study.

* Covers both numerical and experimental aspects of modeling,
analysis and measurement of elastic wave propagation in structural
elements formed from isotropic or composite materials

* Comprehensively discusses the application of the Spectral
Finite Element Method for modelling and analysing elastic wave
propagation in diverse structural elements

* Presents results of experimental measurements employing
advanced laser technologies, validating the quality and correctness
of the developed numerical models

* Accompanying website (href=’../../db/www.wiley.com/go/ostachowicz’>www.wiley.com/go/ostachowicz)
contains demonstration versions of commercial software developed by
the authors for modelling and analyzing elastic wave propagation
using the Spectral Finite Element Method

Guided Waves in Structures for SHM provides a state
of the art resource for researchers and graduate students in
structural health monitoring, signal processing and structural
dynamics. This book should also provide a useful reference for
practising engineers within structural health monitoring and
non-destructive testing.
