Worst-Case Force Visualizations

In this supplement, we provide visualizations of the weakest andsecond weakest regions for every model in the drop test. We alsovisualize the worst-case forces found for each weakest region andreproduce the weakness maps for context. The weakness map isshown on the left, followed by the first and second weakest regions.Not surprisingly, we found the weakest regions to be sensitive to theweak region extraction algorithm (e.g. the choice of �), as differentregions can have similar levels of stress, but the weakness mapschange very little.

We also include two models not tested in the drop test: the trussand the spinnoloid. These are examples of more complicated ge-ometries where our method still finds meaningful weakest regionsand forces.
