Opis:: The subject of the research is analysis of the influence of the damping effect on the dynamic response of a plate. During the tests, the areas of dynamic stability and instability for the plate with and without damping are compared. Besides, exact analysis of the nature of the solution by applying criteria such as phase portraits, Poincar´e maps, FFT analysis, the largest Lyapunov exponents are carried out and found.

Opis:: In the paper influence of the damping in the sandwich bar on its dynamic stability is studied using analytical methods. This paper presents an analysis of dynamic buckling of a sandwich bar compressed by a periodically variable force. In order to determine the dynamic stability of the bar equations of its transverse vibration were formulated. From the equations of motion, differential equations interrelating of the dynamic deflection with space and time were derived. The partial differential equations were solved using the method of separation of variables (Fourier’s method). Then the ordinary differential equation describing the bar vibrations was solved. An analysis of the solution became the basis for determining the regions of sandwich bar motion instability. Finally, the value of the compressive force at which dynamic stability occurs have been calculated.

Opis:: The study analyzed the influence of materials and different types of damping on the dynamic stability of the Bernoulli-Euler beam. Using the mode summation method and applying an orthogonal condition of eigenfunctions and describing the analyzed system with the Mathieu equation, the problem of dynamic stability was solved. By examining the influence of internal and external damping and damping in the beam supports, their influence on the regions of stability and instability of the solution to the Mathieu equation was determined.
