Denting Properties of Aluminum Autobody Components 770199

Dynamic denting tests have been conducted on actual autobody components and on simulated panels fabricated from aluminum and steel sheet at impact velocities of 20 to 125 mph. These experiments give additional evidence that dent depth is a linear function of impact velocity. They also show that autobody components fabricated from aluminum sheet can have equal or improved dent resistance compared to the same components fabricated from the steel alloys currently used. Primary factors to be considered in comparing dynamic dent resistance are sheet thickness, yield strength, modulus of elasticity, density and geometric shape.
