Contact pressure and sliding velocity ranges in sheet metal forming simulations
(2021)
In the last few years many efforts have been carried out in order to better understand what the real contact between material and tools is. Based on the better understanding new friction models have been developed which ...
New drawbead tester and numerical analysis of drawbeads closure force
(Springer, 2021)
Currently, a great deal of controversy exists regarding the real forces generated in drawbeads during sheet metal forming processes. The present work focuses on the analysis of the uplift force. First, a detailed literature ...
The Interaction between the Sheet/Tool Surface Texture and the Friction/Galling Behaviour on Aluminium Deep Drawing Operations
(MDPI, 2021)
The increasing demands for lightweight design in the transport industry have led to an extensive use of lightweight materials such as aluminium alloys. The forming of aluminium sheets however presents significant challenges ...
Soft sensing force measurement approach in sheet metal forming facilities
(IOP Publishing, 2020)
Process stability and facility security are the two main purposes for measuring the force in sheet metal forming facilities. These two purposes look for guaranteeing the good health of the facility avoiding overloads and ...
Analysis of the mechanical and microstructural fluctuations of high-strength steels and their effect on bending angle
(MDPI, 2023)
The quality and complexity demands of manufactured parts in sectors such as automotive and aeronautics lead to narrower process windows. This affects the repeatability and stability of the process, where material properties ...
Numerical analysis of AISI 321 alloy material parameters on rubber pad diaphragm forming
(IOP Publishing, 2022)
Rubber pad diaphragm forming is a technology that uses a rigid die in conjunction with a flexible polyurethane tool and fluid pressure action in order to shape metal sheets. In this process, the action of the fluid forms ...
An automatic thermo-mechanical testing apparatus for metal forming applications
(Elsevier, 2023)
Dynamic testing of materials is necessary to model high-speed forming processes (e.g. hammer forging, blanking, forming, etc.) and crash/impact behaviour of structures, amongst others. The most common machines to perform ...
