Communication avec acte(2019)Strain gradient crystal plasticity (SGCP) represents a very promising way to account for size effects in miniaturized components, thanks to the intrinsic length scale(s) embedded. Most of the existing SGCP models are based ...
-
Communication avec acte(K. Wisniewski; T. Burczynski, 2018)Ductile failure is the main mechanism that limits the formability of thin metal sheets during forming processes. In the current contribution, ductile failure is assumed to be solely induced by the occurrence of localized ...
-
Article dans une revue avec comité de lecture(Elsevier BV, 2021)In this paper, four plastic instability criteria, which are based on the bifurcation theory, are coupled with the GTN damage model for the prediction of diffuse and localized necking. General bifurcation (GB) criterion and ...
-
Article dans une revue avec comité de lecture(Elsevier BV, 2022)In this work, the mechanical properties of hydride diffusion layer were thoroughly researched by nano indentation technique. For the first time, the clear section microstructure of hydride diffusion layer was revealed ...
-
Article dans une revue avec comité de lecture(Springer Science and Business Media LLC, 2021)In this work, a (TiHfZr)(NbTa) 26 (%at) high-entropy quinary alloy has been developed especially for high-temperature superelastic applications and studied over a large range of temperatures. The mechanical properties of ...

Article dans une revue avec comité de lecture(Wiley (Holm Altenbach), 2021)In this paper, we study some qualitative and numerical properties of new equations including the coupled effects of thermal elastic-plastic theory with microtemperatures. We establish the necessary and sufficient conditions ...

Communication avec acte(ACEX, 2016)In this paper, forming limit diagrams (FLDs) for an aluminum alloy are predicted through numerical simulations using various localized necking criteria. A comparative study is conducted for the FLDs determined by using the ...
