STATIC ANALYSIS OF CYLINDRICAL-SHELLS BY USING B-SPLINE FUNCTIONS

This paper is concerned with the application of cubic B//3 spline, quintic B//5 spline functions and eigen-functions which satisfy the boundary conditions to obtaining the approximate solution for the static analysis of a flat cylindrical shell. Unified computational schemes suited for various types of boundary conditions of cylindrical shell are presented in the paper. In comparison with the conventional finite element method and finite strip method, the main features of the present method are higher accuracy, less unknowns, easier programming and more economy in computing storage and time requirement. The numerical results presented are in good agreement with the exact solution.
