Chipping on exposed automobile panels was investigated in the laboratory using a gravel-o-meter and a model tester. The results show that upon impact with a flying stone, the force of friction plays a significant part in causing chipping damage to the panel. Finite element computation based on the elasitic-plastic deformation model considering frictional force revealed that the paint film suffers more chipping damage than the metallic coating does. This is in agreement with the experimental results of the garvel-o-meter test. Chipping damage is greatly affected by the Young's modulus of the chipping primer. Thus the proposed method is confirmed to be useful for analyzing the chipping mechanism and designing the paint system.
