Abstract
A closed form solution is developed in order to analyze the influence of free-edge delaminations on elastically tailored composite laminates . The analysis is based upon a shear deformation theory and a sublamin ate approach. The solution is applied to predict the influence of free -edge delamination on the behavior of a class of laminates exhibiting extension-twist coupling. Comparison of analytical predictions with te st data from laminates with mid-plane and off mid-plane free edge dela minations is performed. The results indicate that free-edge delaminati on can have a significant influence on extension-twist coupling.
