The explosive working of materials in the USSR

Abstract

The studies of the processes related to working the materials by explosive energy were initiated in the Soviet Union during the World War II. The process of armour piercing by shaped charges developed at the beginning of the twentieth century in the United States and in Germany was investigated. The investigations were carried out by a research team of Academician M. A. Lavrentiev in Kiev in 1944–1946 and several modifications of the explosive welding phenomenon were detected'. In the mid-fifties, investigation of explosive powder compaction were begun in Moscow by Professor Yu. N. Riabinin². In the early sixties, M. A. Lavrentiev undertook a large-scale research program on explosive hardening and welding in Novosibirsk¹. Later, explosive powder compaction was also included into the research program³. The first attempts to investigate the strength of the explosive chambers relate to the same period⁴.
