Calculus of variations is a mathematical discipline devoted to finding extreme (largest and smallest) values of functionals – variables that depend on the choice of one or more functions. Calculus of variations is a natural development of the chapter of mathematical analysis devoted to the problem of finding the extremums of functions. The emergenc...
Rationally reinforced products from composite materials are of huge interest to application designing of small-size spacecrafts. Results of numerical modeling of the deflected mode of a standard construction of the small-size spacecraft are presented in this work. It is represented that the weight efficiency of rationally reinforced composites is t...
Sr₍₂₊ₓ₎Bi₍₄₋ₓ₎Ti₍₅₋ₓ₎NbₓO₁₈ materials with x = 0.2, 0.4, 0.6, 0.8, and 1 are synthesized. Investigations of the dielectric constant of the samples reveal an increase in the blurring of the phase transition as the share of titanium ions substituted for niobium ions grows. The Burns temperature and the temperature corresponding to the dielectric perm...
The studies of the dielectric properties of the obtained samples revealed the frequency dispersion and significant smearing of the peak of the real part of the permittivity and the dielectric loss tangent, which indicates the relaxor behavior of the material Sr₂.₈Bi₃.₂Ti₄.₂Nb₀.₈O₁₈, which is not characteristic of pure Sr₂Bi₄Ti₅O₁₈ (without substitu...
The purpose of this research is the synthesis of new layered ferroelectrics, with the general formula Sr₍₂₊ₓ₎Bi₍₄₋ₓ₎Ti₍₅₋ₓ₎NbₓO₁₈ where 0 ≤ x ≤ 1 with the structure of Aurivillius Phases (AP), and the establishment of regularities of the influence of the chemical composition and the degree of structural disorder on the physical properties of these...
Investigation of the influence of substitution of titanium cations Ti⁴⁺ for niobium cations Nb⁵⁺ on the occurrence of relaxor properties of layered perovskite with the structure of Aurivillius phases Sr₍₂₊ₓ₎Bi₍₄₋ₓ₎Ti₍₅₋ₓ₎NbₓO₁₈, as well as the smearing of the phase transition in this material. The study was carried out for 0 ≤ x ≤ 1 with a step of...
According to the standard ceramic technology obtained solid solution (x)BiLi₀.₅Sb₀.₅O₃ — (1−x)Na½Bi½TiO₃. In the temperature range from 23 to 500 °C studied the temperature dependence of the real part of permittivity ε' and tan(δ) at frequencies of 1 to 1,000 kHz in a weak measuring field of about 10 V/cm, which bind to the presence in these sample...
The rapid development of the aerospace industry worldwide, since the 1950s, has created a need for new materials for emerging high-tech products, since many of the requirements for traditional materials (metal alloys) could not be achieved. Light, high temperature resistant materials were required, which would have high mechanical characteristics a...
