Shear coefficient (For solid circular cross-section beam)


Timoshenko beam model takes into account shear deformation and rotational inertia effects, making it suitable for describing the behavior of short sandwich composite beams or beams subject to high-frequency excitation when the wavelength approaches the thickness of the beam. The shear coefficient is dependent on the cross-section geometry of the beam and can be calculated by the Poisson’s ratio.
