On the basis of concept of initial stress, the general equations governing both the finite displacement and the elastic instabilty of thin-walled circularly curved beams with open and closed constant cross section, under axial force, bending and torsion, are formulated by employing the assumption of non-deformable cross section and the well-established assumptions on shear strains. The present theory has been developed considering the difference of curvature of each generator of which curved beams are composed, and hence the formulations are applicable to curved beams of any degree of curvature provided that the overall dimensions and loading conditions are such that assumptions hold reasonably true.
