In the present paper, the bending behaviour of laminated composite and sandwich beams subjected to various sets ofboundary conditions which are simply supported (SS), clamped-simply supported (CS), clamped-clamped (CC) and clampedfree(CF) are investigated by using the Timoshenko beam theory and the Ritz method. In order to solve the problem, theshape functions for axial, transverse deflections and the rotation of the cross-section are presented in polynomial forms. Thevalidation and convergence studies are performed by solving symmetric and anti-symmetric cross-ply composite beamproblems with various boundary conditions and aspect ratios by adding auxiliary functions to the shape functions. The resultsin terms of mid-span deflections, axial and shear stresses are compared with those from previous studies to validate theaccuracy of the present study. The effects of fiber angle, lay-up and aspect ratio on displacements and stresses are studied.
