building blocks of vehicles.
HOLISTIC
Materials selection for applications is an
invigorating and rewarding area of Materials
Engineering. Although there are many tools
for materials selection (such as Ashby
diagrams), ensuring that the right materials
are chosen for a specific purpose is a
creative endeavor. The trade-offs between
various material characteristics can be fluid
and may not be suitable for a deterministic
analysis. For example, how much is one ksi
of yield strength worth for a material? Is it
worth $10 in additional cost per pound,
$100? If a component will lose ductility to
gain the strength, what amount of
substitution will be acceptable?
These material trade-offs are why it is vital
to assess selection from a holistic
perspective, looking at all design criteria and
all properties of a material. The involvement
of materials professionals is ideally
implemented at all stages of pre-design
brainstorming through design, production,
and field operation. Usually there is an
originating owner of a design that will
champion the design through various
disciplines within an organization. A strong
