 Assembly level analysis was performed to accurately resolve contact stresses and properly simulate loading conditions. Visible is the metallic clip to which a 40 lb weight was applied. |  My final revision. Note large interior radii to relieve stress concentration, as well as asymmetrical geometry to account for asymmetrical loading. |  An example of an FEA simulation, with mounting pins and loading clip hidden. A fixed stress color map was assigned to help with visualization. |

Design I Hanger Project
2014
For Junior year Design I class, we were tasked with optimizing a planar, laser cut "coat hanger". A prescribed load was applied by a small metal clip, and the hanger attached to a pegboard. By weight, my design was in the top 20% in the class.
I started with a series of free body diagrams to fully understand the loading conditions. Those served as inputs to an analytical optimization of the beam angles, using a volume-minimizing function. After that, all modeling and FEA was done in Solidworks.
