| Abstract: | Aspects of material selection and innovative concepts of car construction using aluminum as best sui-ted lightweight materials and designs are presented.The dent resistance of automotive body panel has been focused as one of key design parameter and defined more stringent criterion.The affects and test procedures of static dent resis-tance and dynamic dent resistance are both well summarized,and evaluated in details.In the light of the practical ap-plication and technical support,the recent advances in testing and the existing questions are proposed. |
