Structural optimization of vibrating shells E. Hinton, M. Ozakga Department of Civil Engineering, University College of Swansea, Singleton Park, Swansea ABSTRACT This paper deals with the structural optimisation of vibrating shells of resolution and prismatic shells using variable thickness, curved. C(0)< Mindlin Reissner finite elements and finite strips. The accuracy, conver- gence and efficiency of these newly developed finite elements and finite strips are initially explored. Several structural optimisation examples are then presented. INTRODUCTION In the field of optimal design of axisymmetric and prismatic structures the main emphasis and the most significant progress has been with shape optimisation in static situations [1,2]. Many theoretical formulations and approaches for optimal design involving maximisation of the fundamental frequency have been developed for bars [3], arches [4], plates [5] and shallow shells [6]; however, very few applications appear to have been p
