Effect of Fiber Waviness on the Stability of LaminatedPlates

摘要

This paper presents the development of an analytical formulation to predict the effect of fiberrnwaviness on the elastic behavior of composite laminate. A theoretical elastic model was developed tornpredict the lamina elastic properties as function of fiber waviness [1]. A substantial reduction ofrnlamina stiffness is found due to minor waviness. This analysis uses the lamina elastic properties tornpredict the effect of fiber waviness on buckling of composite plate. Percent reduction of criticalrnbuckling load versus fiber waviness is obtained. Examples are presented to substantiate the modelrnpredictions.
