Abstract
In recent years, fiber-matrix composite laminates have been widely used in mechanical structures. Due to functional design requirements, the laminates may contain holes that could cause stress concentration. Unlike isotropic plate, where the stress concentration depend upon geometric parameter and loading conditions, stress concentration factor of fiber-matrix composite is also depend on the anisotropic properties such as fiber direction and angle ply. This paper present intensive studies of the inuence of the fiber direction and angle ply to the stress concentration factors for composite laminate containing circular and elliptical hole under uniaxial loading. The stress concentration factor curves are presented for various angle ply, fiber direction, and geometric parameter. These curves could be used by designer to obtain the optimum design of laminate structure containing hole.
