Grigorenko, д.ф.-м.н. Registration Date 28-11-2025 Organization S.P. Timoshenko Institute of Mechanics of the National Academy of Sciences of Ukraine popup.description1 Analysis of the nature of the distribution of stress fields and dynamic characteristics of inhomogeneous cylinders under different types of loads, vibrations of connected polygonal and perforated plates with different combinations and connection methods, propagation of axisymmetric acoustoelectric waves in a hollow cylinder. Assessment of the effectiveness of the developed new discrete-continuous and discrete numerical approaches. Determination based on the obtained results of calculations of mechanical regularities of the influence of structural inhomogeneity, elastic and electroelastic parameters, boundary conditions on their distribution; comparison of some results with experimental ones and preparation of recommendations for the calculation of structural elements popup.nrat_date 2025-11-28 Close
