Explosion Blast Response of Composites contains key information on the effects of explosions, shock waves, and detonation products (e.g. fragments, shrapnel) on the deformation and damage to composites. The book considers the blast response of laminates and sandwich composites, along with blast mitigation of composites (including coating systems and energy absorbing materials).

Broken down under the following key themes: Introduction to explosive blast response of composites, Air explosion blast response of composites, Underwater explosion blast response of composites, and High strain rate and dynamic properties of composites, the book deals with an important and contemporary topic due to the extensive use of composites in applications where explosive blasts are an ever-present threat, such as military aircraft, armoured vehicles, naval ships and submarines, body armour, and other defense applications.

In addition, the growing use of IEDs and other types of bombs used by terrorists to attack civilian and military targets highlights the need for this book. Many terrorist attacks occur in subways, trains, buses, aircraft, buildings, and other civil infrastructure made of composite materials. Designers, engineers and terrorist experts need the essential information to protect civilians, military personnel, and assets from explosive blasts.

Dynamic Failure of Materials and Structures discusses the topic of dynamic loadings and their effect on material and structural failure. Since dynamic loading problems are very difficult as compared to their static counterpart, very little information is currently available about dynamic behavior of materials and structures. Topics covered include the response of both metallic as well as polymeric composite materials to blast loading and shock loadings, impact loadings and failure of novel materials under more controlled dynamic loads. These include response of soft materials that are important in practical use but have very limited information available on their dynamic response. Dynamic fragmentation, which has re-emerged in recent years has also been included. Both experimental as well as numerical aspects of material and structural response to dynamic loads are discussed.

Written by several key experts in the field, Dynamic Failure of Materials and Structures will appeal to graduate students and researchers studying dynamic loadings within mechanical and civil engineering, as well as in physics and materials science.

This book presents selected papers from the 2nd Workshop on “Durability of Composites in a Marine Environment”, which was held in Brest, France in August 2016. Providing an overview of the state of the art in predicting the long-term durability of composite marine structures, it addresses modelling water diffusion; damage induced by water accelerated testing, including durability in design; in-service experiences; ocean energy; and offshore applications. Ensuring long-term durability is not only necessary for safety reasons, but also determines the economic viability of future marine structures, and as such, the book is essential reading for all those involved with composites in the marine industry, from initial design and calculation through to manufacture and service exploitation. It also provides information unavailable elsewhere on the mechanisms involved in degradation and how to take account of them.

Composites are widely used in marine applications. There is considerable experience of glass reinforced resins in boats and ships but these are usually not highly loaded. However, for new areas such as offshore and ocean energy there is a need for highly loaded structures to survive harsh conditions for 20 years or more. High performance composites are therefore being proposed. This book provides an overview of the state of the art in predicting the long term durability of composite marine structures. The following points are covered:

•       Modelling water diffusion

•       Damage induced by water

•       Accelerated testing

•       Including durability in design

•       In-service experience.

This is essential reading for all those involved with composites in the marine industry, from initial design and calculation through to manufacture and service exploitation. It also provides information unavailable elsewhere on the mechanisms involved in degradation and how to take account of them. Ensuring long term durability is not only necessary for safety reasons, but will also determine the economic viability of future marine structures.
