An intelligent system for predicting HPDC process variables in interactive environment

Paul Xirouchakis, Jitender Kumar Rai

The selection of optimal parameters in high pressure die casting process (HPDC) has been long recognized as a complex nonlinear problem due to the involvement of a large number of interconnected process variables, each influencing the flow behavior of molt ...

Ultra-thick micro-optical components using the PRISM photosensitive flexopolymer

Martinus Gijs, Abdeljalil Sayah, Virendra Kumar Parashar, Venkataragavalu Sivagnanam

We present the photosensitive flexopolymer PRISM as a new promising material for the realization of thick optical components. The PRISM flexopolymer can be directly polymerized using conventional UV exposure and is simply developed in a water-based solutio ...

Two-phase modelling of hot tearing in aluminium alloys using a semi-coupled method

Vincent Mathier

Hot tearing is one of the most severe defects observed in castings, e.g. in billets or sheet ingots of aluminum alloys produced by DC casting. It is due to both tensile strains and a lack of interdendritic feeding in the mushy zone. In order to predict thi ...

Comportement structural des bétons de fibres ultra performants en traction dans des éléments composés

John Wuest

Ultra high performance concretes (UHPFRC) are characterized by a dense matrix and a high fibre content. These materials exhibit exceptional mechanical and durability properties making them an ideal material for rehabilitating existing structures. The prima ...

Rheological Behavior of Al-Cu Alloys during Solidification: Constitutive Modeling, Experimental Identification, and Numerical Study

Jean-Marie Drezet

The rheological behavior of a solidifying alloy is modeled by considering the deforming material as a viscoplastic porous medium saturated with liquid. Since the solid grains in the mush do not form a fully cohesive skeleton, an internal variable that repr ...

A new solution for increasing the efficiency of an electric scooter with supercapacitors through a novel, interleaved multi-channel DC/DC converter

Alfred Rufer, Philippe Barrade, Blaise Destraz

Scooters are a well-established transport system for short distances – particularly within cities. Currently, the majority of scooters are petrol powered. Their engines typically exhibit bad efficiencies and thus contribute to global warming by CO2 product ...

Optimal start-up of micro power generation processes

Benoît Chachuat

uel cell based systems are a promising alternative to batteries in man-portable power generation applications. These micro power generation processes must operate fully autonomously and automatically without the intervention of operators. Operational consi ...

SAMARIS D13 - Report on preliminary studies for the use of HPFRCC for the rehabilitation of road infrastructure components

Emmanuel Denarié, Katrin Habel

The aims of the preliminary study reported in this document were twofold. Firstly, within the context of the application of UHPFRC for the rehabilitation of reinforced concrete structures, to identify the phenomena that require further study with respect t ...

Coalescence and mechanical behaviour of semi-solid aluminium alloys in relation to hot tearing

Piero Daniele Grasso

Semi-continuous direct-chill (DC) casting of aluminium ingots suffers from a very frequent defect which can lead to a strong decrease in productivity: hot tearing. This phenomenon takes place in the mushy state (i.e., at solid fractions, gs, lower than uni ...
