Laminated beams/shafts of annular cross-section subject to combined loading

A novel stress analysis method is developed for the efficient design of radially laminated annular beams/shafts subject to arbitrary load combinations. The analysis is conducted using classic laminate theory (CLT) in conjunction with a mechanics of materials (MoM) approach based on the plane section assumption. Global loads are related to the global deformations and are expressed in terms of the generalised laminate strains in CLT. The analysis is verified against MoM for a homogeneous and isotropic tube. Further validation against the finite element method is shown for general cases in terms of loading and laminate layups with almost perfect agreement.
