The Ashby method is an optimization tool to help selecting the most suitable materials at the lowest cost.

The Ashby method is a tool to map materials according to their physical properties and hence to select the best ones.

The Ashby method is a tool to help selecting the most suitable materials

according optimization criteria on material physical properties with respect to specific design dimensions.

The Ashby method is an optimization tool to help selecting the most suitable materials according optimization criteria on material physical properties only, as well as design constraints.
