Mathematical formulations and numerical solution techniques are presented for the uniform torsional and constrained warping stress analyses of a composite and anisotropic circularly curved structural member. The cross-sectional geometry can be arbitrary. The formulations are based on the theory of elasticity using both stress function and displacement (warping) function approaches. Numerical results are obtained with the finite element method.
