Information × Registration Number 0208U000319, 0107U004016 , R & D reports Title The investigation of nonlinear (tuning) effects which can be induced by the peculiarities of bottom structure when propagating and transforming the equidistant scale wave disturbances popup.stage_title Head Gonchar Anatoliy Ivanovich, Registration Date 23-01-2008 Organization Scientific and technical center of panoramic acoustic systems National academy of sciences of Ukraine popup.description2 Developed and realized the algorithms of response reception on impulse excitation from structurally-acoustical models of bedded bottom. Examined the methods of computation of acoustical fields for different simulation of bottom. Analyzed the problems, which permit to study stationary harmonic oscillation of multilayered massif, containing localized inhomogeneity. Analyzed the problems of nonlinear response of layer on impulse excitation. Product Description popup.authors popup.nrat_date 2020-04-02 Close
