This paper deals with the mathematical model which involves nonlinear dynamics of free surface and contact boundary in a film–substrate system. The model is used for further investigation of the role played by the Taylor-type ...

This study analyzes the evolution of 2 × 105 orbits with initial parameters corresponding to the orbits of comets of the Oort cloud under the action of planetary, galactic, and stellar perturbations over 2 × 109 years. The ...

It is proposed that the fatigue strength of structures in nuclear power plants with a quite long service life be analyzed in two stages: first, the type and location of the process and the effect of basic factors are ...

Magnetization M (T, B) of powder and glassy samples containing carbon nanoparticles is investigated in the interval of temperatures T between ∼ 3 - 300 K and magnetic fields B up to 5 T. Low-field magnetization, M (T), ...

The theoretical aspects and practical findings of the development and commercial implementation of new engineering processes for making art castings of nonferrous alloys are presented. The castings weigh from 0. 1 to 100 ...
