G.R.Liu - Computational Inverse Techniques in Nondestructive Evaluation
Ill-posedness. Regularization. Stability. Uniqueness. To many engineers, the language of inverse analysis projects a mysterious and frightening image, an image made even more intimidating by the highly mathematical nature of most texts on the subject. But the truth is that given a sound experimental strategy, most inverse engineering problems can be well-posed and not difficult to deal with.
Computational Inverse Techniques in Nondestructive Evaluation sets forth in clear, easy-to-understand terms the principles, computational methods, and algorithms of inverse analyses based on elastic waves or the dynamic responses of solids and structures. After describing the features of inverse problems, the authors discuss the regularization methods useful in handling ill-posed problems. The book also presents practical optimization algorithms, including some developed and successfully tested by his research group.
Inverse analyses are fast becoming one of the engineer’s most powerful tools in nondestructive evaluation and testing. With straightforward examples, a wealth of specific applications, and clear exposition written by engineers for engineers, this book offers an outstanding opportunity to overcome any trepidation and begin using inverse analysis in practice.
G. R. Liu received his PhD from Tohoku University, Japan in 1991. He was a Postdoctoral Fellow at Northwestern University, U. S. A. He is currently the Director of the Centre for Advanced Computations in Engineering Science (ACES), National University of Singapore. He is the President of the Association for Computational Mechanics (Singapore), and an executive council member of the International Associate for Computational Mechanics. He is also a Professor at the Department of Mechanical Engineering, National University of Singapore. He has provided consultation services to many national and international organizations. He authored more than 500 technical publications including more than 330 international journal papers and eight authored books, including two bestsellers: “Meshfree Method: moving beyond the finite element method” and “Smoothed Particle Hydrodynamics: a Meshfree Particle Methods”. He is the Editor-in-Chief of the International Journal of Computational Methods and an editorial member of five other journals including the IJNME. He is the recipient of the Outstanding University Researchers Awards, the Defence Technology Prize (National award), Silver Award at CrayQuest competition, the Excellent Teachers Awards, the Engineering Educator Awards, and the APACM Award for Computational Mechanics.
