The work consists of an abstract, 5 sections, a conclusion, a list of literary sources used in the work. The total volume of work is 70 pages, including the main part - 66 pages. The work contains one drawing, 22 references to used literary sources. The object of research is a direct method for solving nonstationary boundary value problems for equations of hyperbolic type. Research methods - to achieve the set goal and solve the problems of theoretical research, methods of mathematical modeling, the main provisions of the theory of wave equations, equations of mathematical physics, the foundations of the theory of generalized quasi-differential equations were used. Theoretical studies were carried out using mathematical modeling and other analytical methods. Analytical methods are effectively used in solving problems. When solving the corresponding specific problems, computer technology and the Maple 13 programming language were actively used. Results in a closed form, the decoupling of boundary value problems for the equation of longitudinal vibrations of a rod in the case of lumpy constant mechanical characteristics and concentrated masses was obtained. The proposed direct method can be used to study oscillatory processes without the use of approximate and operational methods.  Product Description popup.authors Karabyn Oksana O Stasiuk Marta F Chmyr Oksana Yu popup.nrat_date 2021-01-13 Close
