Characterization of the Mechanical Properties of Selectively Embossed Sheet Metal Materials Under Multi-Axial Loads

Abstract The application of embossed structures close to the sheet surface allows for work hardening be introduced into metal materials, leading an improvement in their mechanical properties. So far, this was demonstrated previous research via tensile tests with differently dual-phase steel specimens. Since only reproduce uniaxial loading material, no conclusions can yet drawn about property modification that achieved by near-surface embossing concerning real-life, multi-axial scenarios. To get deeper knowledge deformation behaviour components, it is important consider load cases. In investigations reported paper, a case realized testing bending specimens DP600 and DP800 using three-point device. showed overall maximum force needed test due materials investigated. Further, indicated lower-strength more influenced than higher-strength materials. By simulating process subsequent test, even understanding material could generated.
