Failure by fracture in sheet–bulk metal forming
Journal of Strain Analysis for Engineering Design, 2016This article investigates the possibility of failure by crack-opening mode III (out-of-plane shearing) in sheet–bulk metal forming processes. The investigation makes use of experimentally and theoretically determined fracture-forming limits of aluminium AA1050-H111 sheets with 1 mm thickness, experimental tests in incremental ploughing with a roll ...

Sheet-Bulk Metal Forming of Preformed Sheet Metal Parts
Key Engineering Materials, 2011 Due to ecological and economic challenges there is a rising demand on closely-tolerated complex functional components. Regarding short process chains and improved mechanical properties conventional forming processes are often limited. A promising approach to meet these requirements can be seen in the combination of traditional sheet and bulk metal ...

Influence of Superimposing of Oscillation on Sheet-Bulk Metal Forming
Key Engineering Materials, 2013Due to novel processes like sheet-bulk metal forming, the requirements for sheet metal forming are increased. Sheet-bulk metal forming is a new interconnected process in which the part itself is manufactured by deep drawing and the gearing will be produced with bulk forming in a combined process at room temperature.

Machines and Tools for Sheet-Bulk Metal Forming
Key Engineering Materials, 2011 The demand on closely-tolerated and complex functional components in the automotive sector, like e.g. synchronizer rings, leads to the development of a new process-class named “sheet-bulk metal forming”. Within this technology bulk metal forming operations are applied on sheet metals. In the following two novel approaches considering machines and tools

Sheet-Bulk Metal Forming (SBMF) is an innovative class of forming processes which enables the manufacturing of functional components out of sheet metal. This is achieved by the application of sheet and bulk forming operations on sheets of 1 to 5 mm initial thickness with an intended three dimensional material flow.

Measuring Systems for Sheet-Bulk Metal Forming
Key Engineering Materials, 2015In order to fulfil today’s demands on fast, efficient and sustainable production processes the sheet-bulk metal forming is being developed as a new forming technology within the scope of the SFB/Transregio 73. Characteristically for the sheet bulk metal forming is a three dimensional material flow, which allows for extensive freedom in the design ...

Fatigue Behavior of Sheet-Bulk Metal Formed Components
2020Functional components manufactured by sheet-bulk metal forming will commonly be exposed to cyclic loading during operation. Due to the cold forming during sheet-bulk metal forming, work-hardening occurs and ductile damage is induced in the form of voids in the microstructure. To predict the influence of specific processing parameters on the components’
