Numerical and Experimental Investigation of an Elliptical Paraboloid Shell Model
For practical engineering purpose, a new flat shell element baptized (ACM_Q4SBE1) is presented in this paper. The formulated element can be used for the analysis of thin shell structures; no matter how the geometrical shape might be. Tests on standard problems have been examined. Since, the analysis of thin shell structures has generally been purely carried out on a theoretical basis; it is of importance to present some experimental results of an elliptical paraboloid under uniformly distributed load pressure. The results obtained from both numerical and experimental work are presented. Index Terms— Elliptical Paraboloid, finite element, flat shell element.
A finite element approximation for the analysis of thin shells
Abstract An approximate numerical analysis procedure is presented which is capable of solving thin shells of arbitrary shape, boundary conditions and loading. The shell is idealized as an assemblage of triangular finite elements representing both membrane and flexural stiffness properties, and the solution is carried out by digital computer. Five examples are presented which demonstrate the versatility of the procedure in treating different shell configurations, as well as the accuracy of the results which may be obtained.
