The design of multi-materials requires the determination of several variables: morphology, components and geometric parameters. Previously developed methods help designer making these choices separately because they always lie on a reduction in the number of design variables, as some of them are fixed at the beginning of the study. This paper proposes a method to carry out the simultaneous definition of all these variables in a preliminary design step. The beginning of this work consists in the formalisation of the multi-scale decomposition of the architecture materials. This outline is a guide for the use of databases of materials and architectures, whose combination enables the generation of multi-materials. Within the huge solution space resulting from this approach, a genetic algorithm allows to find optimised materials to fulfil a set of requirements with a limited number of calculations. An analytic example illustrates the efficiency of this method and shows it can provide designers with several propositions of materials.

多材料设计：架构和组件同时选择

多材料的设计需要确定几个变量：形态、成分和几何参数。先前开发的方法有助于设计人员分别做出这些选择，因为它们总是依赖于设计变量数量的减少，因为其中一些在研究开始时就已确定。本文提出了一种在初步设计步骤中同时定义所有这些变量的方法。这项工作的开始在于建筑材料的多尺度分解的形式化。本大纲是使用材料和建筑数据库的指南，它们的组合可以生成多种材料。在这种方法产生的巨大解决方案空间中，遗传算法允许通过有限数量的计算找到优化材料以满足一组要求。一个分析示例说明了这种方法的效率，并表明它可以为设计师提供多种材料命题。
