Analysis of large deflection equilibrium states of composite shells of revolution. Part 2. Applications and numerical results

The behavior of composite shells of revolution with large deflections (load-displacement diagrams and stress states) is studied. The nonlinear boundary value problems for composite shells of revolution, which have been obtained in Part 1 of the present study by means of the asymptotic approximation of Reissner's equations, are analyzed. The numerical solutions of these problems are obtained in several cases of a practical importance. The composite spherical shells with different types of boundary conditions as well as the completed orthotropic ellipsoids of revolution under uniform external pressure and concentrated load are considered in detail. The high accuracy and effectiveness of the obtained asymptotic solutions are demonstrated by means of comparing the asymptotic results with numerical solutions of the original Reissner's equations.
