ESTIMATION OF THE ENERGY EXPENDED FOR SUPERDEEP PENETRATION
S. M. Usherenko,a O. I. Koval',b and Yu. S. Usherenkoc UDC 534.2 We attempted to take a complex approach to estimation of the energy introduced by microparticles into a metallic obstacle and the energy expended for their superdeep penetration realized in the case where they penetrate into the obstacle to a depth of tens or hundreds of millimeters. The disbalance (two- to ninefold) arising in this case between the expended and the introduced energy was explained by the appearance of an additional energy source under the conditions of dynamic compression of microcavities in the process of superdeep penetration. aInstitute of Raising the Level of Professional Skill, Ministry of Education of the Republic of Belarus, 77 Partizanskii Ave., Minsk, 220600, Belarus; bMinsk Institute of Management, Minsk, Belarus; cBelarusian National Technical University, Minsk, Belarus.
