STATIC ANALYSIS OF A CURVED SHAFT SUBJECTED TO END TORQUES

Both the exact closed-form solution and a numerical solution by the di fferential quadrature method (DQM) are obtained to predict the out-of- plane static behavior of a curved shaft subjected to end torques, base d on the curved-beam versions of the classical (Bernoulli-Euler) and. shear deformable (Bresse Timoshenko) beam theories. Deflections, twist angles, bending moments, and twisting moments are calculated for the cases of a circular are of circular cross section with clamped and sim ply supported boundary conditions, and results obtained by the two met hods compared. The DQM gives good accuracy even when only a limited nu mber of grid points is used.
