Structural Design Using Cellular Automata (A Consideration on Derivation of Local Rule)

摘要

This paper presents the structural design scheme by using the concept of cellular automata. A design domain is divided into small square cells and then, thickness of each cell is taken as the design variable. Considering the cells as the finite elements, the stress analysis is performed by the finite element method. The thickness of the cell is modified by the local rule with the states of the cell and the neighboring cells. The present scheme is applied to the two--dimensional elastic problem in order to confirm the validity.
