DYNAMIC DENTING OF AUTOBODY PANELS

Dynamic denting properties of aluminum and steel autobody panels have been experimentally measured under controlled conditions. Material, geometric and dynamic factors have been graphically and statistically evaluated to determine design equations. For impact velocities of 20-60 mph and sheet gauges of 0.027-0.04", dent depths are shown as linear functions of impact velocity. This linear velocity model incorporates sheet thickness, yield strength, density and modulus of elasticity of the allow used, as well as the geometric shape of the fabricated panel. /GMRL/
