Influence of the foil material on the uniformity of the mechanical pressure pulse in electrical explosion of metal foilsJournal of Applied Mechanics and Technical Physics - Tập 56 - Trang 136-142 - 2015
A. N. Grigoriev, E. I. Karnaukhov, A. V. Pavlenko, V. S. Sedoi
This paper presents the results of an experimental study of the temporal
waveforms of the pressure amplitude in different regions of flat electrically
exploded foils of M1T copper, AD1M aluminum, L63 brass, 80NKhS nickel alloy,
VT1-00 titanium, and tin-clad lead. In the case of high-conductivity foils,
explosion starts from the foil ends with a subsequent stronger growth of
pressure in the central... hiện toàn bộ
A Refined Model of Viscoelastic-Plastic Deformation of Flexible Plates with Spatial Reinforcement StructuresJournal of Applied Mechanics and Technical Physics - Tập 62 - Trang 1045-1062 - 2022
A. P. Yankovskii
A refined model of viscoelastic-plastic deformation of flexible plates with
spatial reinforcement structures has been developed. Strains of the composition
materials are assumed to be small and decomposed into plastic and viscoelastic
components. Instantaneous plastic deformation of these materials is described by
the flow theory with isotropic hardening. Viscoelastic deformation obeys the
governi... hiện toàn bộ
Numerical simulation of the dynamics of an intense relativistic beam of charged particlesJournal of Applied Mechanics and Technical Physics - Tập 14 - Trang 786-790 - 1973

A method for the numerical simulation of stochastic processes in intense
relativistic beams of particles moving in electric and magnetic fields is
described. A two-dimensional approximation using “coarse particles” is
considered. The action functions are first tabulated with respect to three
variables. The method combines high speed and good accuracy. The results of a
simulation are presented.
Self-similar solutions of nonstationary equations of a plane laminar magnetohydrodynamic boundary layerJournal of Applied Mechanics and Technical Physics - Tập 7 - Trang 8-11 - 1966
A. G. Boev
Self-similar solutions of nonstationary equations of the boundary layer in
ordinary hydrodynamics are discussed in [1, 2]. In this paper self-similar
solutions of nonstationary equations of a plane magnetohydrodynarnic boundary
layer are sought. In this case, a transformation to curvilinear coordinates of a
certain special form is employed. Its choice is determined by the requirements
essential to... hiện toàn bộ
