Abstract

Although various shell elements has been developed by a lot of researchers, so far not many have very successfully achieved in computational efficiency or modeling accuracy yet. This paper presents a simpler formulation and computational validation of a serial of high order, high performance shell elements. And an analysis program has been completed in FORTRAN on the formulation of nonlinear element tangential stiffness matrix presented. Various numerical examples for 2D membrane structures and bending of plate have been carried out by the program and accurate results hvev been obtained for comparison with other research. This indicate that the formulation for the high order, high performance shell elements is correct and furthermore, the program is reliable, and efficient and convenient for application to high accuracy engineering analysis of any membrane structure and bending problems of shells/plates.
