Although many books on inverse problems already exist, they can be quite mathematical in nature and pay little attention to practical applications. This book forms a bridge between the theoretical foundations and practical applications of nondestructive evaluation methods. With unique emphasis on inverse problems in solid mechanics, it describes in detail the principles, computational methods and algorithms, and practical techniques of inverse analyses using elastic waves and dynamic responses in solids and structures. Applications of advanced computational inverse techniques to electronic system, MEMS, life science and nanotechnology are also introduced. The author also presents a new, "total solution" method for formulating engineering problems and a new regularization method proven very effective for computational implementation.
