摘要
Layerwise theory of Reddy is utilized for investigating free-edge effects in antisymmetric angle-ply laminated shell panels under uniform axial extension Following some physical arguments governing displacement field is divided into local and global parts The former is discretized through the shell thickness by a zig-zag interpolation function while the latter is calculated by a first-order shear deformation theory Local equilibrium equations are then solved through a state space approach Accuracy of the proposed technical solution is subsequently verified by a novel analytical elasticity solution For this end, the problem is analytically solved for specific boundary conditions along the edges The numerical results show excellent agreement between two theories for various composite shell panels (C) 2010 Elsevier Ltd All rights reserved
