Article dans une revue avec comité de lecture(Elsevier, 2020)The weldments made from the 9-12% Cr tempered martensitic steel are associated with a complex microstructure arising from complicated thermal histories of the fusion and heat affected zones. The complicated microstructural ...

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 ...
-
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 ...

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 ...
-
Communication avec acte(Trans Tech Publication, 2016)In the present work, a powerful modeling tool is developed to predict and analyze the onset of strain localization in polycrystalline aggregates. The predictions of localized necking are based on two plastic instability ...
-
Communication sans acte(2016)The prediction of the ductility limit of sheet metals during forming processes represents nowadays and ambitious challenge. To reach this goal, a new numerical approach, based on the loss of ellipticity criterion [1], is ...

Article dans une revue avec comité de lecture(SAGE Publications, 2020)In this work, a multi-scale model established from the concept of periodic homogenization is utilized to predict the cyclic and time-dependent response of thermoplastic-based woven composites. The macroscopic behaviour of ...
