Abstract
Fiber waviness is often found to be a failure initiation site in a structural part. The objective of this research is to evaluate the influence of in-plane fiber waviness on structural response and its sensitivity on a composite beam. Explicit forms of lamina and laminate stiffness and their sensitivity analysis due to fiber waviness are formulated. The change of deflection and natural frequency of a symmetrically laminated composite beam due to fiber waviness was also investigated.Keywords
