Preliminary investigation on homogenization of the thickness distribution in hole-flanging by SPIF
(Elsevier, 2017-06)
A drawback of the hole-flanging process by single-stage SPIF is the non-uniform thickness obtained along the flange. Multi-stage strategies have been used to improve it, however they increase notably the manufacturing time. ...

Numerical study on the thickness homogenization in hole-flanging by single-point incremental forming
(Institute of Physics Publishing, 2018-08)
Incremental sheet forming is a novel technology that has significant benefits compared to conventional forming. However, it is a time-consuming process that is usually carried out in several forming stages to homogenize ...

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 ...

Analysis of the influence of stress triaxiality on formability of hole-flanging by single-stage SPIF
(Elsevier, 2019-02)
Traditionally the fracture in sheet metal forming is characterized by the fracture forming limit (FFL) curve typically obtained by using conventional Nakajima tests. This curve is implicitly assumed a material property. ...

Preliminary Study on the Onset of Necking Detection Using DIT in Tensile Tests
(Trans Tech Publications Ltd., 2022-07-22)
The experimental detection of localized necking is an important issue in sheet metal forming. Today, the most common and extended techniques are strain-based methods using digital image correlation (DIC). The present work ...

Revisiting flangeability in hole-flanging by single-stage incremental forming and conventional process
(PoPuPS (University of LiFge Library), 2021-04)
Recently, hole-flanging by single-stage incremental forming (SPIF) has been proposed as a suitable process to perform hole flanges for small- and medium-sized batches with high flexibility in shape. However, this incremental ...
