Investigation of the second main problem of elasticity for a layer with n cylindrical inclusions
Strength of Materials and Theory of Structures, 2021 При проектуванні конструкцій у вигляді армованого шару доводиться стикатися з ситуацією, коли стержні армування розташовані близько один до одного. У цьому випадку зростає вплив їх один на одного. Для отримання напружено-деформованого стану в зоні контакту шару і включення необхідно мати метод, який би дозволяв отримати результат з високою точністю.

Compact localized states in magnonic Lieb lattices
Scientific Reports, 2023 Lieb lattice is one of the simplest bipartite lattices, where compact localized states (CLS) are observed. This type of localization is induced by the peculiar topology of the unit cell, where the modes are localized only on selected sublattices due to ...

Scattering of SH Waves by a Partially Debonded Cylindrical Inclusion in the Covering Layer
Mathematical Problems in Engineering, 2020 This article presents analytical solutions to the problem of dynamic stress concentration and the surface displacement of a partially debonded cylindrical inclusion in the covering layer under the action of a steady-state horizontally polarized shear wave (SH wave); these solutions are using the complex function method and wave function expansion ...
