Abstract

In this paper, a theoretical analysis is presented for the free vibration behavior of pretwisted thick cylindrical cantilever panels, using the Rayleigh-Ritz approach. The method is based on the three-dimensional elasticity theory with consideration of rotary inertia and shear deformation. Numerical results for pretwisted cylindrical cantilever panels having typical geometries are compared with those available in the literature. The effects of pretwisting and aspect ratio of panels and central angles of the cylinder on the results are also discussed.
