| Abstract: | The dent resistance of a panal for auto body was one of the important considerations when selecting the type or grade of the sheet steel used for the automobile manufacturing, especially for outer body panels. Some mathematical expressions and experimental procedure including its assessment method were empirically derived here. The static denting resistance of flat panel, curved panel with and without work-hardness and strain aging were investigated. Results showed that the method for assesting denting resistance was a rational one for studying dent property of sheet material. |
