This book contains a collection of major research contributions over the last decade in the area of composite materials and sandwich structures supported by the Of?ce of Naval Research (ONR) under the direction of Dr. Yapa D. S. Rajapakse. The Solid Mechanics Research Program at ONR supports research in mechanics of high performancematerialsfortheeffectivedesignofdurableandaffordableNavalstr- tures. Such structures operate in severe environments, and are designed to withstand complex multi-axial loading conditions, including highly dynamic loadings. The - fective design of these structures requires an understanding of the deformation and failure characteristics of structural materials, and the ability to predict and control their performance characteristics. The major focus is on mechanics of composite materials and composite sandwich structures. The program deals with understa- ing and modeling the physical processes involved in the response of glass-?ber and carbon-?ber reinforced composite materials and composite sandwich structures to static, cyclic, and dynamic, multi-axial loading conditions, in severe environments (sea water, moisture, temperature extremes, and hydrostatic pressure). This anthology consists of 30 chapters written by ONR contractors and rec- nized experts in their ?elds and serves as a reference and guide for future research.
This book represents a collection of major research contributions over the last decade in the area of composite materials and sandwich structures supported by the USA Office of Naval Research under the directorship of Dr. Yapa D. S. Rajapakse.
It contains over thirty chapters written by recognized experts in their fields and serves as a reference and guide for future research. Topics covered include: mechanical and failure characterization of composites under static and dynamic loading; failure modes and failure criteria; environmental effects; dynamic effects; post impact behavior; multiscale modeling; nanocomposites; characterization of core materials for sandwich structures under static and fatigue loading; mechanical behavior and failure of sandwich structures; fatigue behavior and durability of composite materials and sandwich structures; core joints in sandwich structures; characterization and failure of marine materials and structures under impulse loading; failure of interfaces under dynamic loading; delamination failure of composite materials and sandwich structures; response of composites and sandwich structures to blast loading and underwater explosions.
