Bending of cross-ply laminated composite beams with various boundary conditions and loading

Abstract

The classical laminate theory is used to create analytic solutions for laminated beams in this study. Several boundary conditions and loads are considered in analytic bending. The boundary conditions taken were hinged-hinged, clamped–clamped and clamped-free and the loading casas taken were center point load and uniformly distributed load. The lamination angles of cross-ply laminated beams were [00]s, [90 90]s, [090]s, and [900]s.The transverse deflection is maximum for lamination angles [90 90]s, [900]s, [090]s, and [00]s respectively for both types of loading, center point load and uniform load. The transverse deflection for center point load is higher than that for uniform for all boundary conditions and laminations.The transverse deflection for fixed-free boundary condition is higher than deflection of hinged-hinged, also deflection of hinged-hinged is higher than for clamped–clamped boundary condition. The results obtained were in excellent agreement.
