| Popis: | The bending analysis of doubly-curved shells has been studied by various methods for some time and nowadays the finite element technique is adopted for this purpose. It is, however, found that the use of the finite element technique often involves a large amount of computer time and memory space for such problems. Thus the Galerkin method, although an old one, is used in a simple form to analyse a conoidal shell, doubly-curved with negative Gaussian curvature, to obtain a quicker solution and to gain a preliminary knowledge of the nature and values of the shell characteristics. Two numerical problems are solved and results are compared with the available finite element ones to show the effectiveness of the authors' approach on the basis of the Galerkin method. |
