Also were considered nonaxisymmetric problems of free vibrations of finite-length cylinders made of FGPM. Effective discrete-continuum numerically-analytical approach based on using of spline - approximation in one of the coordinate directions and of collocation method, and further solution of boundary eigenvalue problem for higher order systems of ordinary differential equations with с variable coefficients, using the discrete orthogonalization and incremental search methods, was suggested.5481 Product Description popup.authors Беспалова Олена Іванівна Григоренко Олександр Ярославович Григоренко Ярослав Михайлович popup.nrat_date 2020-04-02 Close
