Influence of component design on extrusion processes in sheet-bulk metal forming
International Journal of Material Forming, 2019 Abstract Nowadays, the functional integration of workpieces challenges existing forming processes. The combination of established forming processes – like sheet metal and bulk forming – offers the possibility to counter this issue. The application of bulk forming operations on sheet metal semi-finished products, also called sheet-bulk metal forming ...

Correlating Ultrasonic Velocity in DC04 with Microstructure for Quantification of Ductile Damage
Journal of Manufacturing and Materials Processing, 2023 The detection of ductile damage by image-based methods is time-consuming and typically probes only small areas. It is therefore of great interest for various cold forming processes, such as sheet-bulk metal forming, to develop new methods that can be ...
