Layout Optimization of Additional Elements to Create New Composite Materials by Microscopic Structural Design Using CSSL Method

Abstract

In this paper, it is described about a microstructural design method to create a new composite material. In this study, a good mechanical property of a composite material will be realized by a structural design of additional elements. It is assumed that a microscopic structure of reinforcement in a composite material can be modeled to beam structure. By the design system, a location of additional element, which is inserted into a base material of composite material, will be optimized. In order to decide a location of additional element, Convex Subspace Single Linkage Method (CSSL Method) is used. CSSL method is one of the global optimization algorithms. The design system is constructed by using FEM and CSSL method. As one example, the developed design method is applied to a design problem considering microscopic structural design, and a validity of the design system is investigated by a numerical example.
