APPROXIMATE ELASTICITY SOLUTION FOR A LONG AND THICK LAMINATED CIRCULAR CYLINDRICAL-SHELL OF REVOLUTION

An approximate three-dimensional elasticity solution is presented for an infinite, thick, orthotropic as well as laminated circular cylindri cal shell of revolution subjected to distributed pinch load. The valid ity and the accuracy of the results of approximate solution has been e stablished by comparing it with the results of an exact three-dimensio nal elasticity solution for single and multilayered (hybrid) shell of revolution. Numerical results have been presented for cross-ply lamina ted (0/90/0 and 90/0/90) infinite circular cylindrical shell of revolu tion subjected to axisymmetric band and distributed pinch loads. These results have been compared with the classical and first-order shear d eformation theories of Flugge and Donnell to assess the accuracy and l imitations of the two-dimensional shell theories.
