Abstract | The BDS element, which was developed based on a degeneration concept , has been proven to be one o f the most versatile and simplest finite element for the static solutions of thick and thin shells of arbitrary geometry. The performance of t h is element in free vibration and elastic stability problems is examined for general shell applications. The formulations of the mass matrix and the geometric stiffness matrix o f the BDS element are presented. Then, the finite element program FEAP is employed for the standard finite element analysis , where a typical eigenvalue problem is solved by the subspace iteration eigen solver, SIJENS. Several examples are tested to demonstrate the competence o f the element. The numerical results indicate that the shell element performs accurately in free vibration and elastic stability problems of either thick or thin shells. |
