Shock, Impact and Explosion: Structural Analysis and Design
Springer | ISBN: 3540770674 | 2008-12-01 | PDF | 1366 pages | 99 Mb
The dynamics of shock, impact and explosions are an important consideration in the design of structures. This book provides a detailed and illustrated study of structural dynamics of almost all types of shocks, impacts and explosions.
After a comprehensive survey of accidents and explosions, the author covers all areas of basic structural dynamics and provides a full treatment of impact dynamics. Two chapters are devoted to a detailed analysis and numerical modelling for explosions occurring in air underground and underwater as well as formulations for the finite element analysis of shock impact and explosion. The last part of the book deals with many detailed case studies on structures of numerous materials like steel, composites, and concrete structures.
Shock, Impact and Explosion is devoted to research and practising engineers, designers, technologists, mathematician and specialists in computer-aided techniques.

Hydronamics of Explosion presents the research results for the problems of underwater explosions and contains a detailed analysis of the structure and the parameters of the wave fields generated by explosions of cord and spiral charges, a description of the formation mechanisms for a wide range of cumulative flows at underwater explosions near the free surface, and the relevant mathematical models. Shock-wave transformation in bubbly liquids, shock-wave amplification due to collision and focusing, and the formation of bubble detonation waves in reactive bubbly liquids are studied in detail. Particular emphasis is placed on the investigation of wave processes in cavitating liquids, which incorporates the concepts of the strength of real liquids containing natural microinhomogeneities, the relaxation of tensile stress, and the cavitation fracture of a liquid as the inversion of its two-phase state under impulsive (explosive) loading. The problems are classed among essentially nonlinear processes that occur under shock loading of liquids and may be of interest to researchers in physical acoustics, mechanics of multiphase media, shock-wave processes in condensed media, explosive hydroacoustics, and cumulation.

Explosion Protection: Heinrich Groh
Butterworth-Heinemann | ISBN: 0750647779 | 2003-01 | PDF (OCR) | 544 pages | 9.21 Mb
This book makes Hazardous or Electrical Area Classification simple. In plants processing flammable materials, every effort is made to avoid the escape of such materials and in addition, stringent measures are taken to exclude sources of ignition. A complex array of standards surround this topic which has lead to an overly conservative approach being taken. This type of approach means that much more expensive electrical apparatus than is necessary is installed.
To avoid this unnecessary expenditure, Dr Groh clearly explains the relevant standards, so that accurate assessment of the risks associated with hazardous areas is possible. He also identifies possible ignition sources and methods of designing apparatus which do not cause sparks thereby maintaining safety.
* Covers must-have information regarding IEC/CENELEC standards in electrical or hazardous area classification
