DEVELOPMENT OF TOOLS FOR MULTI-MATERIAL DESIGN

摘要

Multi-material design implies the selection of various parameters such as the nature of the components, their morphology (or architecture), their volume fractions... Although selection methods have been developed for monolithic materials, a single method dealing with all these parameters hasn't been created yet. This paper describes several tools that can guide the designer in this task. The first one consists in a statistical analysis of the material properties to see whether some requirements are incompatible. In this case, the result allows the separation of these requirements and helps the components selection. Then, another study deals with the selection of the components when the architecture of the multi-materials is known. The important benefit of this method is a filtration of the candidates that decreases drastically the number of solutions that have to be evaluated. Finally, a last paragraph shows how an architecture can be selected and optimised.
