Asymmetric Single Point Incremental Forming of sheet metal
2005
The use of computers in manufacturing has enabled the development of several new sheet metal forming processes, which are based upon older technologies. This paper describes modifications that have been made to traditional forming methods such as conventional spinning and shear forming, forming processes in which deformation is localized. Recent advances have enabled this localized deformation to be accurately controlled and studied. Current developments have been focused on forming asymmetric parts using CNC technology, without the need for costly dies. Asymmetric Incremental Sheet Forming has the potential to revolutionize sheet metal forming, making it accessible to all levels of manufac…
The circle in the relationship between space and body. Photo-essay based on Isidro Blasco and the BAPNE method
2015
En el presente artículo se muestra un estudio visual sobre el espacio educativo universitario en el que se desarrollan enseñanzas sobre percusión corporal. Como marco metodológico se escoge la Investigación Educativa Basada en las Artes Visuales empleándose la obra de un artista como referente conceptual y metodológico. La investigación queda marcada tanto por la referencia visual a la obra de Isidro Blasco – especialmente con la obra “Shanghai planet 2009”-; como por los paralelismos establecidos entre el objeto de estudio de esta investigación -el análisis espacial- y los focos de interés desvelados por los críticos de arte respecto a la obra de este artista. Mediante un discurso visual f…
A numerical approach for the modelling of forming limits in hot incremental forming of AZ31 magnesium alloy
2021
AbstractMagnesium alloys, because of their good specific material strength, can be considered attractive by different industry fields, as the aerospace and the automotive one. However, their use is limited by the poor formability at room temperature. In this research, a numerical approach is proposed in order to determine an analytical expression of material formability in hot incremental forming processes. The numerical model was developed using the commercial software ABAQUS/Explicit. The Johnson-Cook material model was used, and the model was validated through experimental measurements carried out using the ARAMIS system. Different geometries were considered with temperature varying in a…
Graphic proposal for the great hall of the Palace of the Counts of Oliva
2021
[EN] The now-demolished Palace of the Counts of Oliva, in the province of Valencia (Spain), was an outstanding example of late Gothic and early Renaissance architecture and art. Its great hall was particularly impressive, with rich, complex decoration that constituted a cultural milestone linked recently to the ‘Germanías’, or Brotherhoods. Through research conducted in image and document collections, a graphic reproduction of the room has been produced, with special emphasis on its frieze. The procedures and techniques used in this process are examined here, before a final contemplation of the possible uses for these results.
Comparative Study for Springback Prediction on Single Point Incremental Forming Process
2014
The present paper proposes a comparative study in order to determine the springback in single point incremental forming process. Using the Ls-Dyna software the process was simulated for one piece in frustum of pyramid shape. In the end of the explicit dynamic analysis, it was run, using the same software, an implicit analysis to determine the springback. For this comparison study we selected four different shell formulations. The results obtained in this simulation were compared with those obtained experimentally for the same part. The experimental research was conducted on a robot and, on the opposite side of the machined surface, an Aramis measuring optical system was placed to allow the …
Comparison between aluminum alloys behavior in incremental sheet metal forming process of frustum pyramid shaped parts
2021
Abstract Single point incremental forming is a new emerging technology, used mainly for prototype development or small series production, with good prospects in industrial implementation. However, the parts manufactured through this process often presents low accuracy, thus the industrial implementation is yet limited. Incremental forming process can be done with the help of different technological equipment, such as industrial robots and numerically controlled machines. Since the process is still in development phase, it is a good practice to use finite element analysis software packages in order to reduce time and costs to produce accurate parts. The aim of this paper is to investigate th…
Methanol fuel processor and PEM fuel cell modeling for mobile application
2010
International audience; The use of hydrocarbon fed fuel cell systems including a fuel processor can be an entry market for this emerging technology avoiding the problem of hydrogen infrastructure. This article presents a 1 kW low temperature PEM fuel cell system with fuel processor, the system is fueled by a mixture of methanol and water that is converted into hydrogen rich gas using a steam reformer. A complete system model including a fluidic fuel processor model containing evaporation, steam reformer, hydrogen filter, combustion, as well as a multi-domain fuel cell model is introduced. Experiments are performed with an IDATECH FCS1200™ fuel cell system. The results of modeling and experi…

This article deals with the connection between theory and practice in the context of a further education programme (FEP) (KigaDance) for nursery teachers based on contemporary dance education. The ...
Un viaje de ida y vuelta al otro mundo. El Cabaret del Diavolo de Gino Gori y Fortunato Depero en Roma (1922-1925)
2023
The Roman cabarets linked to Futurism were meeting places where the programme of the manifesto Ricostruzione futurista dell’universo was applied. Following the experiences of Bragaglia and Marchi at the Circolo delle Cronache d’Attualità and the setting by Giacomo Balla at the Bal Tic Tac, the entrepreneur and poet Gino Gori commissioned Fortunato Depero to decorate the Cabaret del Diavolo. Based on Dante’s Commedia, Depero would create an integral design of three spaces that configured an allegorical inverted reading of the Florentine poet’s journey to the afterworld. Its originality and careful advertising made the cabaret one of the representative spaces of the Roman nightlife which, des…
