Results of FEALess stress in the middle
Therefore room for optimization of material thickness

Future work
• Apply FEA with entire frame
• Run more cases with dynamic loading
• Model tubes of frame with varying cross-section (thinner in darker blue areas)
• Add welding at contacts and add gussets
• Perform corrections to Pro-E model with
the cross-section removed from the places where the tubes intersect
