Free Vibrations in a Rotating Generalized Elastic Hollow Solid Sphere

Received Date:03 August 2022, Accepted Date:06 October 2022, Published Date:14 November 2022


Objective: To investigate the free vibrations in a rotating elastic hollow solid sphere. Method: The method of plane harmonic solution is employed to solve the basic governing equations of rotating elastic solid. Findings: Three types of frequency equations named as coupled frequency (CF) (Radial and tangential) equations, radial frequency (RF) equation and tangential frequency (TF) equations are derived. Novelty: Under the MATLAB program, the numerical computations have been performed for a particular material. Frequency versus angle is shown graphically for rotating and non-rotating material. TF and CF curves are inverse proportional to the angular rotation. Coupled frequencies are slower than the tangential frequencies.
