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 boundar y value problems for composite shells of revolution, which have been obtain ed in Part 1 of the present study by means of the asymptotic approximation of Reissner's equations, are analyzed. The numerical solutions of these pro blems are obtained in several cases of a practical importance. The composit e spherical shells with different types of boundary conditions as well as t he completed orthotropic ellipsoids of revolution under uniform external pr essure and concentrated load are considered in detail. The high accuracy an d effectiveness of the obtained asymptotic solutions are demonstrated by me ans of comparing the asymptotic results with numerical solutions of the ori ginal Reissner's equations.
