Materials Selection Methodology – Lesson 2

As we saw in Lesson 1, materials are needed at many stages in the design process. But how do we take our design requirements and use them to select materials? To do this, we will use the Ashby Materials Selection methodology as described in Chapter 4 of our reference text. The steps can be seen the figure below.

In this lesson, we will review all steps of the methodology and go through an example of the translation step, where we take our design requirements and identify key elements such as function, constraints, objectives, and free design parameters that we can use during materials selection.
