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

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
