On the effective peek application for customized cranio-maxillofacial prostheses: An experimental formability analysis
(Elsevier, 2023)
Single Point Incremental Forming (SPIF) is a dieless and flexible forming technology that allows performing complex shapes and presents a high economic payoff for low production series. In this context, this research ...

Tube Expansion by Single Point Incremental Forming: An Experimental and Numerical Investigation
(MDPI, 2021-09)
In this paper, we revisit the formability of tube expansion by single point incremental forming to account for the material strain hardening and the non-proportional loading paths that were not taken into consideration ...

On the Determination of Forming Limits in Polycarbonate Sheets
(MDPI, 2020-02)
By proposing an adaptation of the methodology usually used in metal forming, this paper aims to provide a general procedure for determining the forming limits, by necking and fracture, of polymeric sheet. The experimental ...

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. ...

Experimental investigation of polycarbonate sheets deformed by SPIF: formability, micro-mechanisms of failure and temperature analysis
(Elsevier, 2023)
This article presents an experimental research performed on a polycarbonate sheet deformed by single point incremental forming (SPIF). The analysis is implemented within the framework developed in previous research work ...

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 ...

A Market-Based Analysis on the Main Characteristics of Gearboxes Used in Onshore Wind Turbines
(MDPI, 2017-10-25)
Even though wind energy is one of the most mature renewable technologies, it is in continuous development not only because of the trend towards larger wind turbines but also because of the development of new technological ...

On the Analysis of the Contact Conditions in Temporomandibular Joint Prostheses
(Hindawi Limited, 2018-04)
Temporomandibular joint replacement (TMJR) is a complex surgical procedure in which the artificial joints available must assure the anatomical reconstruction and guarantee a good range of the natural temporomandibular joint ...
