  • Based on the first-order shear deformable beam theory, a refined model for composite beams containing a through-the-width delamination was presented, and the deformation at the delamination front was considered. Different from the ordinary delaminated beam theory, each of the perfectly bonded portions of the new model was constructed as two separated beams along the in terface, and the plane section assumption at the delamination front was released. The governing equations of the delaminated portions and bonded ones were established, combined with continuity conditions of displacements and internal forces. The solutions of delaminated composite beams with different boundary conditions, delamination locations and sizes were shown in excellent agreement with the finite element results, which demonstrate the efficiency and applicability of the presentmodel.
