In unibody construction, which type of damage is uncommon?

• A. Primary damage
• B. Side sway damage
• C. Twist damage
• D. Diamond damage

Answer: (D)

In unibody construction, the whole shell is one integrated structure that shares and distributes crash forces across many panels and members. Because of this, damage from a collision usually shows up as twisting of the body, side sway from a side impact, or the primary damage at the point of impact where energy is absorbed first. A diamond-shaped pattern of damage isn’t typical because the energy isn’t confined to a neat four-point indentation; the load spreads through crumple zones, stiffeners, and panel seams, leading to more irregular wrinkling, buckling, or deformation along the panels and joints rather than a clean diamond. So diamond damage is uncommon in unibody construction.
