About the Book: Nonlinear Ultrasonic and Vibro-acoustical Techniques for
Nondestructive Evaluation
This multi-contributed volume provides a practical, applications-focused
introduction to nonlinear acoustical techniques for nondestructive evaluation.
Compared to linear techniques, nonlinear acoustical/ultrasonic techniques are
much more sensitive to micro-cracks and other types of small distributed
damages. Most materials and structures exhibit nonlinear behavior due to the
formation of dislocation and micro-cracks from fatigue or other types of
repetitive loadings well before detectable macro-cracks are formed.
Nondestructive evaluation (NDE) tools that have been developed based on
nonlinear acoustical techniques are capable of providing early warnings about
the possibility of structural failure before detectable macro-cracks are formed.
