摘要：
An efficient approximate solution for calculating the complete state of stress around a circular hole in symmetric cross-ply laminates under a set of far-field bending and torsion is presented. This approach is based on the boundary-layer theory in conjunction with Lekhnitskii's solutions for anisotropic plates and the principle of minimum complementary energy. All of the boundary conditions around the hole edge of each ply and traction continuity at the ply interface are exactly satisfied. Numerical examples are compared with the NASTRAN finite element solutions to demonstrate the efficiency and accuracy of the current method.
