DESIGN CRITERIA FOR THE DENT RESISTANCE OF AUTO BODY PANNELS

The dent resistance of doubly curved rectangular panels in various steels and aluminum alloys was studied. Dent depth on the order of magnitude of the panel thickness was determined. An empirical equation was developed that relates dent resistance to the yield strengths, modulus of eleasticity, metal thickness, and panel geometry of stiffness. Dent resistance increases with an increases in yield strength, thickness and panel radii of curvature, but decreases with an increase in modulus of elasticity and stiffness.
