Box 11365-9567, Azadi Avenue, Tehran, Iran Journal Article 2013 09 29 Within the elasticity theory the reduced form of displacement field is obtained for general cross-ply composite laminates subjected to a bending moment. The first-order shear deformation theory of plates and Reddy’s layerwise theory are then utilized to determine the global deformation parameters and the local deformation parameters appearing in the displacement fields, respectively. For special set of boundary conditions an elasticity solution is developed to verify the validity and accuracy of the layerwise theory. Finally, various numerical results are presented within the layerwise theory for edge-effect problems of several cross-ply laminates under the bending moment. The results indicate high stress gradients of interlaminar stresses near the edges of laminates. https://scientiairanica.sharif.edu/article_3490_6d57996fa1c73b6c179139e8a2e77711.pdf
