Blast

Needham, Charles E. Blast Waves, SPRINGER, BERLIN, 030 ISBN: 3642052878
The primary purpose of this text is to document many of the lessons that have been learned during the author's more than forty years in the field of blast and shock. The writing therefore takes on an historical perspective, in some sense, because it follows the author's experience. The book deals with blast waves propagating in fluids or materials that can be treated as fluids.It begins by distinguishing between blast waves and the more general category of shock waves. It then examines several ways of generating blast waves, considering the propagation of blast waves in one, two and three dimensions as well as through the real atmosphere. One section treats the propagation of shocks in layered gases in a more detailed manner.The book also details the interaction of shock waves with structures in particular reflections, progressing from simple to complex geometries, including planar structures, two-dimensional structures such as ramps or wedges, reflections from heights of burst, and three-dimensional structures.Intended for those with a basic knowledge of algebra and a solid grasp of the concepts of conservation of mass and energy, the text includes an introduction to blast wave terminology and conservation laws as well as a discussion of units and the importance of consistency.

Su, Yu: Blast Mitigation of Masonry Walls by Various Retrofit Technologies Numerical Simulation of Strengthened Unreinforced Masonry Walls by New Retrofitting Technologies for Blast Loading, VDM VERLAG DR. MÜLLER, September 2010, Besorgungstitel - vorauss. Lieferzeit 3-5 Tage. ISBN: 3639290615
Masonry buildings exhibit the vulnerability of poor blast-resistant capacity with little ductility. Aiming to find effective strengthening solutions to enhance masonry walls against explosion, this roject focused on studying the performance of retrofitting techniques, such as EB FRP and NSM FRP. However, the performance of the EB and NSM strips retrofits on masonry walls against blast loading is poor. This research shows that, such retrofits failed in shear or bending between strips. Hence, several other new materials, such as spray-on polyurea and aluminium foam, were also studied for mitigation of blast effect. To increase ductility of the wall, a new technique known as spray-on polyurea was employed. It was found that the capability of absorbing stain energy was the key factor that influenced performance of blast mitigation. A new energy absorbing material, aluminium foam, was applied to the masonry walls. To investigate the effectiveness of different types of retrofitting materials, debonding failure level and wall failure level were identified and then extended to greater range of pressure and impulse relationship.

Advances in Rice Blast Research provides a complete overview of the research undertaken on the rice-blast pathosystem. This book gathers in one volume the most recent works on rice blast fungus genetics and molecular biology of pathogenicity, rice blast fungus population studies, and genetics and molecular biology of rice resistance to blast, including resistance gene cloning. It also presents the latest results on resistance breeding and resistance management strategies, epidemiology and disease management. This book is a must for plant pathologists and breeders working on rice blast and also to plant pathologists and breeders dealing with fungal diseases in general, because the rice-blast pathosystem is a model in plant pathology.

Faruqi, M. A.; Grisel, J. Efficient Design of Blast Wall Panels, LAP LAMBERT ACADEMIC PUBLISHING, Juli 2011, Besorgungstitel - vorauss. Lieferzeit 3-5 Tage. ISBN: 3845413875
Corrugated panels are currently used in petrochemical facilities as an economic means to provide blast protection to personnel and other valuable assets. In this book, parametric studies were conducted on the various elements (e.g., compression flange, depth, angle of corrugation, etc.) of a corrugated blast wall using static nonlinear finite element analyses and dynamic nonlinear single degree of freedom analyses. During the static analyses, panel characteristics such as ductility and strength were explored and nonlinear load-deflection curves were generated. The load-deflection curves were then used to observe the response of each wall using a single degree of freedom time-step integration method. Results showed that some blast wall profiles have a greater ability to limit reaction loads transferred to the primary structure, reduce material cost/ panel thickness, and/or protect nearby assets. Understanding how the different elements of a corrugated blast wall affect its structural response to a blast enables the engineer to design efficient passive protection systems that dissipate blast energy efficiently.
