内容提要:	"Presents the state of the art in the modelling, analysis and experimental investigation of elastic wave propagation using a technique of rapidly increasing interest and development. Addressing an important issue in the field of guided-wave-based damage identification and structural health monitoring, Guided Waves in Structures for SHM presents the modelling, analysis and experimental investigation of elastic wave propagation in engineering structures made of isotropic or composite materials. The authors begin by summarising present-day knowledge on elastic wave propagation in solids, focusing on challenges associated with developing efficient numerical methods and verifying them experimentally.
内容提要:	They then progress to describe modelling and analysis using the Spectral Finite Element Method-based approach, presenting the results of numerical tests of elastic wave propagation in structural elements of diverse types ranging from rods through beams, disks, plates and coatings to 3D structures. The section devoted to experimental research describes applications of laser technology for measuring elastic wave propagation in real-life structural elements. Addresses both numerical analysis and experimental research in a single volume. Presents state-of-the-art numerical models based on the Spectral Finite Element Method and experimental research employing laser technologies.
内容提要:	Coverage includes an introduction to theory of
