Materials are chosen based on their strength-to-weight ratio and environmental resistance: An Ultimate Guide To Aerospace Sheet Metal Fabrication
: Flat sheets are inherently flexible. Designers introduce stiffening ribs , beads , and joggles (small offsets that allow parts to overlap smoothly) to increase a part's resistance to buckling without adding more material. Aerospace Sheet Metal Design
: Every gram matters. Designers use techniques like lightening holes (cutouts that remove excess material) and flanged holes to maintain stiffness while reducing mass. Materials are chosen based on their strength-to-weight ratio
