Multi‐Criteria Material Selection of Monolithic and Multi‐Materials in Engineering Design

Multi‐materials are combinations of monolithic materials in a chosen configuration and scale. They can help populate the material property space and fill areas monolithic materials cannot reach. This paper presents a novel approach to compare the performance of monolithic materials and multi‐materials in multi‐criteria design problems, with the results being visualised through exchange constant charts. In this paper, a particular type of multi‐materials, sandwich panels, is selected to demonstrate the approach.
