Static and Free Vibration Analysis of Cylindrical Shells with Shear and Normal Deformations Effects
(0) In this work we develop equations of motion for an orthotropic shell with arbitrary geometry and the stress-strain state is represented by equations of three-dimensional elastic theory.The high order shear and normal deformations theory(HSNDT)of shells is used to analyze the shell in static and dynamic cases.The three-dimensional representation of the equations is reduced to the two-dimensional one by applying the principle of virtual displacements incorporated with the expansion of displacement components in the form of polynomial series in the coordinate system normal to the neutral surface of the shell.The modified boundary conditions for standard cases of mounting shell(clamped,simply supported and free edges)are applied.In this paper,the method is used for static and natural vibration analyses of a circular cylindrical shell.By using Laplace transform to calculate the stress-strain state,the number of arbitrary constants in the integration form of the differential equation system is halved.The values of natural frequencies are defined by Bubnov – Galerkin variational method.
