Bending of a Cross-Ply Laminated Composite Beam Under a Sinusoidal Transverse Loading

Abstract

Bending of a laminated composite beam under to a sinusoidal loading is carried out for simply support boundary condition for a specific cross-ply stacking sequence. To demonstrate the accuracy of the analytical results, a computer-aided engineering (CAE) approach is used. In the analytical solution, a unified shear deformation theory with a parabolic shape function is used. The longitudinal and vertical displacements, normal and shear stresses, namely, the bending stresses of analytical and CAE solutions are obtained and compared with the literature. Although two different methods are used in the study, the analysis results converge to the reference values. The variation of the displacements, normal and shear stresses are illustrated in the graphics with respect to the beam length and thickness respectively.
