Objective: To develop methods and approaches for the mathematical modeling of structures inhomogeneous structure and creation of software for the numerical solution of spatial problems of mechanics of composite structures and heterogeneous materials under static and dynamic deformation with visualization of the processes. Development of the asymptotic methods for solving the problem of forced oscillations of geometrically nonlinear functionally graded materials imperfect shallow shells thickness, depending on the time and on the nonlinear dynamics of satellite and aircraft s concentrated mass, dependent on time. The new approaches, methods and software in the calculation of structures from heterogeneous and composite materials, namely, to obtain effective mechanical characteristics of the fiber composite, methods of construction of discrete models and finite element stiffness matrices. The developed approaches have been used for the calculation of shell structures in the framework of the two economic contracts with the state enterprise M.K.Yangel State Design Office "Yuzhnoye" and implemented at the Institute of Geotechnical Mechanics of National Academy of Sciences of Ukraine to determine the components of the stress-strain state of rubber-isolators. Sectors of application: engineering, transportation, building, aerospace.
