Application of Explosives in Metal Forming

Abstract

The use of explosives in deformation process is one of the most interesting and still insufficiently explored areas. This unconventional technology has an increasing use because of being much cheaper and not requiring expensive tools, machines. Explosive as a source of energy has a low price as well. This paper involves deep-drawing explosion technology as well as one of the tools which is used for this technology. High-alloy steels are used to make dies strength, concrete, plastics and others. Also types of media that can be used in processes of explosion are mentioned. Because the calculated mass of required explosives can differ up to 200%, three distinct expressions are suggested, as well as expression for calculating of detonation rate by Dautriche method.
