On the superposition of solutions of the (3 + 1) dimensional Charney–Obukhov equation for the ocean
Autor: A. G. Kudryavtsev, N. N. Myagkov
Publikováno v: Physics of Fluids. 35
New exact solutions describing Rossby waves and vortices in ocean propagating along the zonal direction at a constant velocity are found for the (3 + 1)-dimensional nonlinear Charney–Obukhov equation. These solutions are a partial superposition of

Autor: A. G. Kudryavtsev, N. N. Myagkov
Publikováno v: Physics of Fluids. 34:126604
New exact spatially localized solutions on the background of a zonal flow, propagating along the zonal direction at a constant velocity, are found for the (3 + 1)-dimensional nonlinear Charney–Obukhov equation describing Rossby waves and vortices i

Fragmentation model of a rapidly expanding ring with arbitrary cross-section
Autor: N. N. Myagkov, V. A. Goloveshkin
Publikováno v: Meccanica. 54:1219-1224
A model has been proposed to estimate the average number of fragments produced by ductile fracture of a rapidly expanding ring with arbitrary cross-section. The model uses a minimum number of constants characterizing the material properties of the ri

Model for the Interaction of a Rigid String with a Deformable Target
Autor: V. A. Goloveshkin, N. N. Myagkov
Publikováno v: Russian Metallurgy (Metally). 2019:294-300
A model is proposed to describe the interaction of a rigid penetrator (string) with a deformable target at high-velocity impact. The problem is considered in the plane deformation approximation. The target material is assumed to be incompressible and

Scaling Invariance and Characteristics of the Cloud of Spherical Projectile Fragmentation Products upon High-Velocity Impact on a Thin Mesh Shield
Autor: N. N. Myagkov
Publikováno v: Journal of Experimental and Theoretical Physics. 126:50-63
In this paper, we consider the problem of the fragmentation of an aluminum projectile on a thin steel mesh shield at high-velocity impact in a three-dimensional (3D) setting. The numerical simulations are carried out by the smoothed particle hydrodyn

Critical behavior for impact fragmentation of spherical solid bodies sensitive to strain rate
Autor: N N Myagkov
Publikováno v: Journal of Statistical Mechanics: Theory and Experiment. 2021:113201
We consider the impact fragmentation of two spherical solid bodies sensitive to strain rate in a three-dimensional (3D) setting. We use both dimensional analysis and numerical simulations by smoothed-particle hydrodynamics (SPH) method to shed light
