The chapter shows that beam elements rotate to conform to the curved shape. Shear deformation and rotary inertia both lower the natural frequency from that predicted by the flexural beam theory, and they become increasingly important in the higher modes of short beams. The natural frequencies and ...
Results for the frequency parameters are compared with results published in the literature. Modes of vibration are also included. The solution of the eigenproblem gives the eigenvalues of the system and their corresponding eigenvectors. The natural frequencies are the square root of the eigenvalues, ...
