Book Description
Seven materials that are currently being considered for use as backpacking around deeply buried protective structures and silos were investigated for the effects of particular phenomena which may be present or occur in the environments in which the materials may be used. Certain physical characteristics necessary for a better understanding of a material's behavior when used as a backpacking were also determined. The materials studied included three low-density concretes, two foamed plastics, foamed glass, and foamed sulfur. Each material was investigated for its strength-deformation characteristics and limitations, the effects of attack by groundwaters of different compositions, the effects of freezing and thawing, constrained consolidation, permeability, cyclic loading, constrained modulus of elasticity, brittleness, compatibility, and resistance to attack by fungi and bacteria.

Book Description
Vibration is a common phenomenon when a structure is exposed to one or multiple mechanical or environmental actions, always at great cost to lives and to the economy. In order to reduce the adverse impact of vibration, vibration mitigation materials and structures have recently been at the center of attention. This book “Structure Vibration: Vibration Mitigation Materials and Structures” as the tip of the iceberg, provides a window to let people know about the flourishing of this young field. Twelve original research papers and one review paper have been included in this book to represent the recent development of vibration mitigation technology. The vibration mitigation material manufacture process, testing, analysis, and application have completely thoroughly studied. We wish more cutting-edge achievements will arise to benefit mankind and continually promote the development of vibration mitigation materials and structures.

Book Description
This volume discusses the fundamental dynamic behaviour of granular materials, in particular cohesionless sand, when subjected to shock and blast wave loading. The contents of the book are mainly divided into three parts based on the type of loading imparted to the granular materials: Shock-wave loading (step pulse); Air-blast loading (Friedlander wave); Buried-blast loading. It provides a comprehensive review of the available testing methods, along with the necessary diagnostic measurements for material characterization, making it useful for researchers working in the area of blast protection and Impact engineering.

Book Description
The behavior of a buried structure subjected to blast loading must be evaluated on the basis of the loads reaching the structure. Research has shown that the use of a properly designed backpacking material placed around the structure dissipates a portion of the shock energy present in the free field, thereby reducing the magnitude of the forces reaching the structure. The response of the backpacking then and that of the structure are completely interdependent, and the design of one cannot be considered without the design of the other. Based on the results of laboratory research, three materials--(a) a naturally occurring friable aggregate, (b) a foamed plastic, and (c) an insulating concrete--are currently being utilized in a prototype experiment to evaluate their shock-dissipating and stress-transfer characteristics. The results of this experiment along with other factors such as cost, availability, and ease of placement will enlighten the future outlook for backpacking materials placed around buried structures.
