Excitation) Vibrations of Shells displacement and rotation. The first study on vibrations of circular cylindrical shells is attributed to Reissner (), who isolated a single half-wave (lobe) of the vibration mode and analyzed it for simply supported shells; this analysis is therefore only suitable for circular panels.   Nonlinear vibrations of thin circular cylindrical shells are investigated in this paper. Based on Love thin shell theory, the governing partial differential equations of motion for the rotating circular cylindrical shell are formulated using Hamilton principle. Taking into account the clamped-free boundary conditions, the partial differential system is truncated by using the Cited by:

Loughborough University Institutional Repository Free vibration analysis of stiffened circular shells This item was submitted to Loughborough University's Institutional Repository. The receptance method is applied to the analytical study of the free vibrations of a simply supported circular cylindrical shell that is either empty or filled with an inviscid, incompressible fluid and with lumped masses attached at arbitrary positions. The receptance of the fluid-filled shell is obtained using the added virtual mass approach to model the fluid-structure interaction.

  Eigenvalues and modes of vibrations for a thin shell weakened by a hole are studied taking into account a new approach to constructing a dynamic finite-dimensional model. It is shown that at a relatively small notch, the inherent characteristics of the shell with a hole can be found by solving the problem on vibrations of the shell with an added mass that is equal to the Cited by: 6. A variational full-field method is presented in this paper for the free vibration analysis of open circular cylindrical laminated shells supported at discrete points. A differential equation in matrix form is developed using the first-order shear deformable theory of shells, and rotary inertia is .

The differential equations of motion are solved directly with the use of simple Fourier series as the modal displacement functions. Book Description. With increasingly sophisticated structures involved in modern engineering, knowledge of the complex vibration behavior of plates, shells, curved membranes, rings, and other complex structures is essential for today’s engineering students, since the behavior is fundamentally different than that of simple structures such as rods and beams.

In order to study the free vibration of simply supported circular cylindrical shells, a semi-analytical procedure is discussed in detail. In this technique, beam function is used as an approximation for simply supported boundary conditions. A literature review reveals that beam functions are used extensively in predicting natural frequencies of shells.

The shell is made up of uniform layers of isotropic or specially orthotropic materials. The equations of motions in longitudinal, circumferential and transverse displacement components, are derived using extension of Cited by: 3.
