Condition assessment and characterization of materials and structures by means of
nondestructive testing (NDT) methods is a priority need around the world to meet the challenges
associated with the durability maintenance rehabilitation retrofitting renewal and health
monitoring of new and existing infrastructures including historic monuments. Numerous NDT
methods that make use of certain components of the electromagnetic and acoustic spectrum are
currently in use to this effect with various levels of success and there is an intensive
worldwide research effort aimed at improving the existing methods and developing new ones. The
knowledge and information compiled in this book captures the current state of the art in NDT
methods and their application to civil and other engineering materials and structures. Critical
reviews and advanced interdisciplinary discussions by world-renowned researchers point to the
capabilities and limitations of the currently used NDT methods and shed light on current and
future research directions to overcome the challenges in their development and practical use.
In this respect the contents of this book will equally benefit practicing engineers and
researchers who take part in characterization assessment and health monitoring of materials
and structures.
