Abstract
The problem of maximizing the fundamental frequency of free vibrations of a structure is considered in the general setting of a simultaneous optimization of material and structure. As an extension of recent wor k by Bendsoe et al. (1993), the design variables include the constitut ive tensors that characterize material properties. The analytical form of the extremal material problem is derived together with a considera bly simplified auxiliary equivalent problem.
