On the Use of Strain Path Independent Metrics and Critical Distance Rule for Predicting Failure of AA7075-O Stretch-Bend Sheets
(MDPI, 2020-08)
The strain-based forming limit curve is the traditional tool to assess the formability of metal sheets. However, its application should be restricted to proportional loading processes under uniform strain conditions. ...

Analysis of formability in conventional hole flanging of AA7075-O sheets: punch edge radius effect and limitations of the FLC
(Springer, 2020-03)
Hole flanges are commonly manufactured in mass production by conventional press-working. In an industrial context, the process limits are usually evaluated by means of the Limiting Forming Ratio (LFR), which defines the ...

Stretch-flanging of AA2024-T3 sheet by single-stage SPIF
(Elsevier, 2021-03)
Flanging is a forming process that is commonly used in many high technology industrial applications such as the manufacturing of thin-walled aircraft structures as wing ribs that are formed using rubber-pad forming during ...

On the Use of Maximum Force Criteria to Predict Localised Necking in Metal Sheets under Stretch-Bending
(MDPI, 2017-11-02)
The maximum force criteria and their derivatives, the Swift and Hill criteria, have been extensively used in the past to study sheet formability. Many extensions or modifications of these criteria have been proposed to ...

Analysis of Flangeability by Single-Stage SPIF and Press-Working in AA7075-O Sheet
(American Society of Mechanical Engineers (ASME), 2021-01)
Recently, the research interest of hole-flanging has turned from conventional press-working to single-point incremental forming (SPIF) as a viable process for small- and medium-sized batches. Both technologies have been ...
