Conference paper


An element was developed previously which is capable of predicting the undamped natural frequencies of thin elastic shells of revolution. The above element possessed a number of features, e.g. a change in element characteristics could be achieved by a change in the input data. The above formulation has now been updated so that the internal degrees of freedom have been condensed. Also an efficient eigenvalue-economiser routine has been developed to reduce the iteration time. The routine is capable of selecting the masters analytically at a given cut off frequency. These have facilitated the storage and running of the above routines on modern micro-computers. A number of well established examples have been tackled and the results are given in the text.
