Deflection of multilayered composites containing wavy fibers

Abstract

This research involves the development of theoretical model to investigate the effect of fiber waviness on the deflection of multilayered composites plates. This paper analyzes the effect of the in-plane fiber waviness on the deflection of clamped composite plate. The wavy fiber induces change in lamina elastic properties, which influence the laminate extensional, coupling, and bending stiffness. This analysis uses finite difference method, and Ritz technique to solve for deflection of multilayered composites. An example is illustrated to substantiate the model predictions. A clamped laminate containing fiber waviness subjected to transverse loading is analyzed and results of deflection versus fiber waviness are obtained.
