A layer containing area of kink or arcuate bend the piecewise continuously inhomogeneous and nonuniform thickness layer composite cylinder and the cylinder of the nonlinear material is investigated. Algorithms and complex computer programs for numerical implementations of computational and visualization of information are constructed. Regularities of influence parameters of inhomogeneities and complicated physical and mechanical properties on the dispersion, kinematic, power and energy characteristics of the propagation, reflection and refraction of elastic waves are generalized. Recommendations of applied research to the practical using of established fundamental effects in geoacoustics, ultrasonic detection and acoustoelectronics are given.5481 Product Description popup.authors Єлагін Олексій Володимирович Білик Микола Васильович Бай Олексій Володимирович Моісеєнко Ігор Олексійович Носок Віталій Йосипович Сальков Ігор Григорович Тимчук Олег Сергійович Фоменко Максим Володимирович popup.nrat_date 2020-04-02 Close
