Dynamic analysis of an orthotropic viscoelastic cylindrical panel of variable thickness

The intensive development of the modern industry is associated with emergence a variety new composite materials. Plates, panels, and shells variable thickness made such materials are widely used in engineering machine building. Modern technology for manufacture thin-walled structures any configuration makes it possible to obtain given variation law. Such subjected various loads, including periodic ones. Nonlinear parametric vibrations an orthotropic viscoelastic cylindrical panel investigated without considering elastic wave propagation. To derive mathematical model problem, Kirchhoff-Love theory geometrically nonlinear setting. properties described by hereditary Boltzmann-Volterra three-parameter Koltunov-Rzhanitsyn relaxation kernel. problem solved Bubnov-Galerkin method combination numerical method. For implementation algorithm computer program were developed Delphi algorithmic language. panels under external load investigated. influence physical, mechanical, geometric parameters on behavior, as thickness, inhomogeneous material, load, studied.
