TRANSFORMED-SECTION MODEL FOR COMPOSITE BEAMS BASED ON AXIAL STIFFNESS
A method of analysis to determine axial and bending stress distributions in open-section beams composed of fiber-composite layers is presented. The method is based on the transformed-section concept, and the effects of Poisson's ratios and in-plane shear are taken into account. Numerical results are presented for an I-shaped cross section with various fiber orientations, and are compared to those obtained from lamination theory, and the conventional transformed-section method which neglects the effects of Poisson's ratios and shear coupling. The transformed-section model and numerical solutions are detailed. Stress-strain relations for unidirectional layers and equilibrium equations are presented.
