Influence of strain strengthening on steel sheet dent resistance

WU Hua1,JIANG Hao-min2 (1.Sales Division,Baosteem-NSC/Arcelor Automotive Steel Sheets Co.,Ltd., Shanghai 201900,China;2.Baosteel Research Institute,Baoshan Iron & Steel Co.,Ltd.,Shanghai 201900,China)  
With the increasing requirements to the lightening of auto body,as an important index of material selection of outer panel,the sinking resistance is noticed by the designer.The dent resistance tests of four steel grades with different yield strength were carried out in different pre-strains.It is shown that the strain strengthening will obviously improve the strength of sheet steel and the local dent resistance.With the increasing of yield strength of steel sheet,the load in certain dent depth will increase and the dent resistant ability will be strengthened further.The dent resistant ability will be improved by the strain strengthening in the stamping process.
