The first complete introduction to health monitoring,
encapsulating both technical information and practical case studies
spanning the breadth of the subject.
Written by a highly-respected figure in structural health
monitoring, this book provides readers with the technical skills
and practical understanding required to solve new problems
encountered in the emerging field of health monitoring. The book
presents a suite of methods and applications in loads
identification (usage monitoring), in-situ damage identification
(diagnostics), and damage and performance prediction (prognostics).
Concepts in modelling, measurements, and data analysis are applied
through real-world case studies to identify loading, assess damage,
and predict the performance of structural components, as well as
examine engine components, automotive accessories, aircraft parts,
spacecraft components, civil structures and defence system
components.
In particular the book:
* provides the reader with a fundamental and practical
understanding of the material;
* discusses models demonstrating the physical basis for health
monitoring techniques;
* gives a detailed review of the best practices in dynamic
measurements including sensing;
* presents numerous data analysis techniques using model- and
signal-based methods;
* discusses case studies involving real-world applications of
health monitoring;
* offers end-of-chapter problems to enhance the study of the
topic for students and instructors; and
* includes an accompanying website with MATLAB programs providing
hands-on training to readers for writing health monitoring model
simulation and data analysis algorithms.
Health Monitoring of Structural Materials and Components
is an excellent introductory text for newcomers to the subject as
well as an excellent study tool for students and lecturers.
Practitioners and researchers, those with a greater understanding
and application of the technical skills involved, will also find
this essential reading as a reference text to address current and
future challenges in this field. The wide variety of case studies
will appeal to a broad spectrum of engineers in the aerospace,
civil, mechanical, machinery and defence communities.
