Performance indices for materials describe the mechanical efficiency of a component under a given mode of loading: The higher the performance index, the lower the mass of the component for a given mechanical requirement. Material selection charts (Ashby, 1989) offer a graphical means of comparing performance indices for a wide range of materials. Performance indices are described. Micromechanical models for behaviour of cellular materials are used to suggest novel microstructural designs for cellular materials with improved performance. Three novel microstructural designs, described in companion papers, have been fabricated and tested. Results of the tests indicate that the new microstructures have higher values of some performance indices than those of the solids from which they are made.
