On the basis of an expression for the scattering phase function of an individual fiber, relations modeling radiative properties of fibrous composites are obtained. We calculate the temperature state of a layer of such a material under condition of ex

A model is proposed to calculate stresses in a glass layer with gas impurities heated by thermal infrared radiation. Calculations were performed for a layer with a diatomic impurity of nitric oxide and a triatomic impurity of water. It is shown that

We state the problem of stress-optimization of regimes for heating a piecewise-homogeneous cylindrical glass shell from the surrounding medium and heat sources and give an analytic/numerical solution of the problem under given bounds on the parameter

We propose a mathematical model for quantitative description of the diffusion process of a gaseous admixture in a solid body (a solid solution) due to electromagnetic radiation in the infrared range. We write out the original relations that describe

We study the thermostressed state of a round nonferromagnetic plate subject to the action of a steady electromagnetic field produced by a system of external ring-shaped currents. It is determined that a decrease in the winding radius of a single-loop
