“…In a real EC, the distances from the side wall and cupola to the charge center may be different, so the stress-strain state of the shell may differ significantly from the uniform one. The strain-stress measurements performed in the explosive chamber KV-2M, KVG-16 described below showed that the real maximal stresses in the EC shell could differ by 1.5 -2 times from the averaged values calculated by the formulas (6-8) [5,6]. This effect is caused by the fact that, during shell oscillations, flexural waves converge in the cupola center, their amplitudes are added, and stresses are concentrated.…”

“…The formulas (1,2,5) give an important relation for the evaluation of the EC shell mass needed to localize the explosion of the specific mass M e 2 2 In this formula σ a means an allowable stress in the shell. For example, taking σ a = 200 MPa for a steel shell, we have M/M e = 1.2 10 3 .…”

“…If the shell is spherical, σ 1 and σ 2 are circumferential stresses and are equal to each other, thus the equations(1,2,5) are used to calculate the common value σ = σ 1 = σ 2 , and we have…”

The paper presents the principles of stress calculations for metal shells sustaining internal impulse loading. The designs of metal explosion chambers (EC) are described; examples of their utilization in scientific research and engineering applications are presented. Aside from conventional methods of the EC use, i.e. explosion welding, explosion hardening, powder compacting, synthesis of new materials, etc., recently the EC has found ever-widening applications in recycling discarded parts containing explosives, such as ammunition. The metal EC provides localization of every explosion damaging effect, improves the safety of works, and enables performing blasting operations both in industrial and laboratory conditions.

The paper presents the experience in designing and manufacture of explosion chambers for researching purposes and technological applications gathered in Lavrentyev Institute of Hydrodynamics of Siberian Branch of Russian Academy of Sciences. The peculiarity of the developed explosion chambers is that they are all-metal units with a long service life (10 thousand explosions and more); they completely isolate blast effects (shock wave, seismic wave, etc.) and hence can be installed in laboratory rooms and industrial premises and, when necessary, can be disassembled and moved to a new place of exploitation. Presented examples illustrate the application of the explosion chambers in production of new materials, articles, and for elimination of ammunition.Keywords: explosion chamber (EC), computational model, composed shell, technological applications Praca prezentuje doświadczenia w projektowaniu i wytwarzaniu komór detonacyjnych dla celów naukowych i zastosowań technologicznych zebranych w Instytucie Lavrentyeva w Syberyjskim Instytucie Hydrodynamiki, Rosyjskiej Akademii Nauk. Cechą charakterystyczną zastosowanych komór detonacyjnych jest to, że są one wykonane całkowicie z metalu oraz posiadają długą gwarancję żywotności (10 000 detonacji, lub więcej); dodatkowo całkowicie izolują od otoczenia skutki detonacji (fale uderzeniowe, fale sejsmiczne, itd.) i stąd można je instalować w pomieszczeniach laboratoryjnych, na terenach powierzchni przemysłowych, i kiedy jest to konieczne, mogą zostać zdemontowane i przeniesione w inne miejsce. Przedstawione przykłady ilustrują zastosowanie komór detonacyjnych przy wytwarzaniu nowych materiałów i detali.
