Article dans une revue avec comité de lecture(Elsevier, 2020)Wire-arc additive manufacturing has become an alternative way to produce industrial parts. In this work 15 kg walls are built with an effective building rate of 4.85 kg/h using an ER100 wire providing good tensile properties ...

Strain-path dependent hardening models with rigorously identical predictions under monotonic loading Article dans une revue avec comité de lecture(Elsevier, 2021)Accurate sheet metal simulation often requires advanced strain-path dependent material models, in order to predict the material response under complex loading conditions, including monotonic, reverse and orthogonal paths. ...

Communication avec acte(Elsevier BV, 2020)Surface integrity induced by machining process affects strongly the performance of functional products, for instance, the fatigue life as well as the resistance to stress corrosion cracking. Consequently, it is relevant ...

Article dans une revue avec comité de lecture(Elsevier, 2020)This paper presents experimental and numerical investigations to study spatial-temporal distributions of strain heterogeneities within a FV566 turbine rotor steel subjected to high temperature conditions. Strain field were ...

Article dans une revue avec comité de lecture(Elsevier, 2020)In most voided metallic materials, the failure process is often driven by the competition between the phenomena of void coalescence and plastic strain localization. This paper proposes a new numerical approach that allows ...

Formability prediction of substrate-supported metal layers using a non-associated plastic flow rule Article dans une revue avec comité de lecture(Elsevier, 2021)When manufacturing flexible devices, it is quite common that localized necking appears due to the low ductility of the metal sheets used. To delay the inception of such localized necking, several industrial companies have ...

Communication avec acte(2016)In this paper, both the bifurcation theory and the initial imperfection approach are used to predict localized necking in substrate-supported metal layers. The self-consistent scale-transition scheme is used to derive the ...
