Static bending response of rotating beams with partially resting on an elastic foundation

Abstract

Based on a new theory of high-order shear strain, this paper examines the static bending response of a beam rotating about a fixed axis and resting only partially on an elastic base. The formulations are established using the finite element method, which eliminates the need for a shear correction factor. This demonstrates that computational theory is preferable to Mindlin's first-order shear strain theory. The article investigates the effect of certain specific parameters on the static bending response of this beam, particularly the foundation length, rotational speed, and distance from the beam to the axis of rotation, by establishing the beam's reliability. There are numerous scientific and practical implications of the findings for rotating beam structures.
