Assessment of advanced Taylor models, the Taylor factor and yield-surface exponent for FCC metals
Zhang, Kai; Holmedal, Bjørn; Manik, Tomas; Saai, Afaf (Journal article; Peer reviewed, 2019)High-resolution crystal plasticity-finite element method (CPFEM) simulations are performed to provide new reference values of the Taylor factor M and the isotropic yield surface exponent for high stacking fault energy ... -
Deformation Texture Evolution in Flat Profile AlMgSi Extrusions: Experiments, FEM, and Crystal Plasticity Modeling
Manik, Tomas; Marthinsen, Knut; Zhang, Kai; Imani Aria, Arash; Holmedal, Bjørn (Peer reviewed; Journal article, 2021)In the present work, the deformation textures during flat profile extrusion from round billets of an AA6063 and an AA6082 aluminium alloy have been numerically modeled by coupling FEM flow simulations and crystal plasticity ... -
EVOLUTION IN TEXTURE AND ITS THROUGH-THICKNESS VARIATIONS IN Al-Mg-Si-EXTRUSIONS: EXPERIMENTS AND MODELLING.
Zhang, Kai; Marthinsen, Knut; Holmedal, Bjørn; Aukrust, Trond; Segatori, Antonio (Chapter, 2018) -
A fully kinetic phase diagram-coupled multicomponent columnar-to-equiaxed grain transition model with an application to additive manufacturing
Du, Qiang; M'Hamdi, Mohammed; Reiersen, Magnus; Hovig, Even Wilberg; Zhang, Kai (Peer reviewed; Journal article, 2024)The columnar-to-equiaxed transition (CET) is known to impact crack formation during the additive manufacturing of metallic alloys. While previous experiments have shown that CET is tunable via its alloying elements, a ... -
