Abstract

Design of continuum structures using local rule E. Kita, T. Toyoda & T. Isomura School of Informatics & Sciences, Nagoya University, Japan Abstract This paper describes the structural optimization scheme based on the cel- lular automata. The optimization process is carried out with the local rule. This paper presents the new rule which not only deletes cells but also adds cells near the stress concentration points. Finally, the present scheme is applied to the shape optimization of the continuum structures. Numerical results show that the present scheme is relatively independent on the ini- tial profile of the structure and that the computational cost can be reduced fairly. 1 Introduction Cellular automata are considered as the powerful tool for the simulation of the complex systems such as the liquid flow, the traffic flow and so on. Recently, some researchers have been studying the structural optimization scheme based on the concept of the cellular automata[l, 2, 3, 4, 5]. In t
