| Abstract | ||
| ABSTRACT The solution of Composite Spherical Shells subjected to different external loading and boundary condition are investigation and analysis by the application of the classical composite-material theory. In this research are used Chebyshev series in matrix form to reformulate the differential equations of equilibrium of a composite spherical shell . Two problem are solved by using Chebyshev theory, the first problem are solved laminated spherical shell under uniform external pressure with open ( "o=10o) , the results obtained for maximum stress is (5.298-5.563 N/m) and maximum moment is (1.189-1.99 N.m/m).The results are compared with available published results and confirmed mach well. The second problem is solved for a supported shells under unite edge line load with different ("o=30o and 80o ), the results is seen the stress for laminated composite shells concreted near the pole or near the equator and the bending is localized around the edges. | ||
