Structural Optimization Based On CA
Author(s)
Eisuke Kita, Tetsuya Toyoda
Abstract
This paper presents the structural optimization method based on the concept of
cellular automata (CA). An initial design domain is divided into small square
cells, and then the cell thickness is taken as the design variable for the
optimization. The stress analysis of the structure is performed by the local rule
with stress distribution. In this paper, the local rule is derived from vanishing the
first variation of the objective function. The present scheme is applied to the
two-dimensional elastic problem.
1 Introduction
Cellular automata (CA) are considered to be powerful tools in the analysis of
complex systems [1, 2, 3, 4]. Some researchers, on the other hand, have been
studying the application of cellular automata to structural optimization [5, 6,
7].
