Ashby plot for materials index of (E2/p), suitable for a Beam of minimum weight and prescribed stiffness. On the Log E versus Log p graph, slide the materials index line of slope 2 upwards to optimize the stiffness to weight for a beam. The solid (i.e., non-greyed out) materials above the materials index line are suitable candidates for a beam application, since they are stiff and have low densities. [For reference, the density of water is 1000 kg/m] Perform Materials Selection for a variety of design scenarios. 1) Fill in the table below, by creating the appropriate Ashby Plot and entering the top material choice for the respective material index. Comment on the choice, e.g. whether you agree with the top choice for the design scenario. This will give you an idea of the utility of creating a short list using this technique and then selecting by applying other criteria that may not be captured by the given material index.
