Abstract : The purpose of the work is to apply the point-matching technique to the stress and deflection analysis of fibrous composite materials; to develop a computer program, based on the method, to solve transverse normal loading problems involving fibers with cross-sections having two axes of symmetry in a staggered array; and to demonstrate the use of the computer program. The separate constituent materials are assumed to be linearly elastic, isotropic, and homogeneous. The bonding between the fiber and matrix materials is assumed to be perfect. The equations of plane strain theory are presented and the Michell solution in polar coordinates is used. The point-matching method is used to satisfy the boundary conditions in the least squares sense at a finite number of discrete points. (Author)
