Computer Simulations in Adaptive Structural Formation Including Anisotropic Properties

Abstract

This paper deals with a simulation method of adaptive structural formation including anisotropic properties. The proposed method is based on a cellular automaton model which consists of isotropic cells. We propose the concrete method that generates an orthotropic structure considering nine kinds of elastic modulus and principal axes of elastic anisotropy under multiple loading conditions. The method renews the moduli and the axes of each cell according to the principal stresses. For validity of the method, three-dimensional simulation is performed under three loading conditions and the computed anisotropic structure is presented.
