Friction Conditions in Sheet-Bulk Metal Forming
Procedia Engineering, 2011 AbstractThe ongoing trend towards the increasing component functionality and closely-tolerated complex functional components shows the limits of classical sheet and bulk metal forming operations. The combination of sheet and bulk metal forming operations to the new process class of sheet-bulk metal (SBMF) operations gives the possibility to produce the

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 ...
