FINITE ELEMENT ANALYSIS OF AXISYMMETRICAL SHELLS OV COMPOSITE MATERIAL
Abstract
A doubly curved surface of revolution element has been developed for the direct stiffness analysis of axisymmetrical shells of composite material. The assumptions of classical shell theories regarding preservation of the normal and thickness to radius ratio have been abandoned in the development of the stiffness matrix. Thickness, temperature, material properties, and load intensity are allowed to vary along the generator of the shell; material properties may vary through the thickness. A digital computer program has been written to accomplish the computations. In the program, the shape of the shell is described by point by point numerical values; thus the generator can be of quite general shape and the element can take on the shape of the shell without the usual approximations. Numerical results show close correlation with known solutions of a number of isotropic shells and with experimental data of a hydrostatically tested composite material shell. It is believed that the technique developed presents an improvement over the existing finite element analyses.
