Abstract : Methods of analysis are developed for a laminated circular cylindrical shell composed of generally orthotropic materials subjected to arbitrary axially symmetric mechanical loadings. Elastic shell theory including transverse shear deformation is used. By treating each lamina individually, and imposing stress and displacement boundary conditions at the interfaces between laminae, the governing equations for the individual laminae are combined, yielding the interlaminar shear and normal stresses as explicit dependent variables. The results are presented in the form of a parametric study for a generally orthotropic circular cylindrical shell comprised of two and three laminae, subjected to a uniform pressure with both clamped and simply supported boundary conditions. Variables in the parametric study include laminate geometry, fiber orientation, stacking sequence and material properties. A computer program has been formulated to expedite calculations of the analytical solution. (Author)
