Materials Selection in Mechanical Design by M.F.Ashby

Mechanical Design. Mechanical components :- have mass- carry loads- conduct heat and electricity- exposed to wear and corrosion- are made of materials- have a shape- must be manufactured. Inter- relations. . Evolution of Engineering Materials. The Design Process. To develop a methodology for selecting materials and processes which is design led, i.e. the design uses as inputs the functional requirements of the design. .
