Abstract

A closed-form analytical solution is developed for analyzing laminated composite curved beam with fiber waviness. Explicit expressions for evaluating equivalent axial and bending stiffness are formulated based upon modified lamination theory and taking into consideration the structural deformation characteristics of beam with narrow section. The maximum radial stress is computed for a laminated composite curved beam with fiber waviness under four-point bending at any given location. The maximum radial stress results were in a good agreement with numerical results obtained by ABAQUS. It is concluded that the present approach is an efficient method for analyzing laminated composite curved beam with fiber waviness.
