![]() ![]() ![]() Any engineering component has one or more functions: to support a load, to contain a pressure, to transmit heat, and so forth. The first task is that of translation: converting the design requirements into a prescription for selecting a material and process to shape it. In collaboration with colleagues at Cambridge University and Granta Design Ltd, UK we have developed material property charts, selection methodologies that enable this match, and that interface with other engineering design tools. Material selection involves seeking the best match between the property-profiles of the materials and that required by the design. And, of course, they need common sense: the ability to use experience and knowledge of the world at large to recognise inspired choices and to reject those that are impractical. Fourth, they need access to data for material attributes and - since the quantity of data is large - computer-based tools to enable their implementation. Third, they need methods for selecting from these menus the materials and processes that best meet the requirements of a design. Second, an understanding of the origins of these properties and of the ways that they can be manipulated. ![]() ![]() What do they need to know to choose and use materials successfully? First, a perspective of the world of materials - polymers, glasses, ceramics, composites and so forth - and of processes that can shape, join and finish them. ![]()
