Evaluation of damage and TNT equivalent of ammunition, explosive and pyrotechnics

摘要

A large explosion in general produces widespread destruction because of associated shock and blast waves. An explosion is a rapid release of energy in atmosphere and is characterised by the formation of shock wave subsequently resulting into a blast wave. The blast wave propagates in the media and interacts with structure produces large deformations. Methods to quantify the explosion of ammunition, high explosive and pyrotechnic and also the principles involved in determining their TNT equivalent with respect to blast are described. The experimental technique for determining the TNT equivalent of ammunition, pyrotechnic and explosives is discussed. The blast damage correlations as applicable to various types of targets are also discussed.
