| Abstract Scope |
Selective embossing of sheet metal blanks, prior processing, offers the possibility of locally modifying material properties. Small indentations applied on the sheet metal surface by a punch lead to increased material strength due to the induced strain hardening. Moreover, such locally embossed sheet metals show an enhanced process window with regard to forming processes and an improved performance under different loading conditions. The experimental study presented in this paper investigates the bending properties of high-strength steel sheets em-bossed on the tension or the compression surface of the bent blank. The effect of embossing on the bending resistance of two different materials (DP500 and TRIP780) were analyzed by varying the embossing patterns by density and depth. As a result, bending forces required in the tests rise when increasing the proportion of em-bossed surface. Therefore, the paper reveals potentials of local embossing with regard to a specific modification of bending properties of sheet metal components, thus enabling their use in lightweight constructions. |
