Tymoshenka Institute of Mechanics of the National Academy of Sciences of Ukraine popup.description1 Development of an analytical approach to the study of wave processes in acoustic and elastic half-space and layer under an arbitrary nonstationary load applied to its surface, and determination of the peculiarities of the processes of propagation and multiple reflection of excited waves. Development of methods for joint optimization of mass and energy parameters and transient trajectories of interorbital vehicles with low thrust propulsion systems during maneuvering in the central gravitational field. Development of an analytical approach to the study of contact interaction of rigid flat and non-planar dies, including heated ones, with a piezoelectric half-space, establishing characteristic regularities of contact stress distribution under the dies, assessment of the influence of force and electric fields on contact parameters. popup.nrat_date 2024-12-09 Close
