Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2  Computational models of geometrically nonlinear dynamic deformation of shell elements of cylindrical structures made of functionally gradient composite materials with nano-reinforcement have been developed. An analysis of self-oscillations of various thickness nanocomposite cylindrical shells in a supersonic gas flow is carried out. Two-dimensional models for calculation are proposed to study the stress-strain state of nanocomposite plate structures under static and dynamic loads. A computational model of fairing based on the composite representation of load-bearing structural elements, a method for determining the characteristics of the composite structure orthotropic layers, a method for calculating dynamic processes, and computer studies of the launch vehicle head fairing during separation have been developed.
