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 ... -
Comparative study of the effects of galvanic corrosion on the strength and the failure of aluminium and stainless steel bolted joints
Saai, Afaf; Delhaye, Virgile Roger; Lange, Torstein; Furu, Trond; Aamot, Kristian; Lein, John Erik (Peer reviewed; Journal article, 2023)This paper investigates the effects of bimetallic insert on corrosion, material degradation, loading capacity, stress distribution, strain distribution and failure of aluminium-stainless steel lap shear bolted assemblies. ... -
Coupled fluid-solid modelling of the valve dynamics in reciprocating compressors
Ervik, Åsmund; Saai, Afaf; Berstad, Torodd; Meyer, Ole; Tsuji, Takuma; Oku, Tatsuya; Hattori, Kazuhiro; Yamada, Kazuya; Delhaye, Virgile Roger; Nekså, Petter (Chapter, 2022)A novel method coupling computational fluid dynamics (CFD) and finite element method (FEM) was developed to account for the complex physics of the reciprocating compressor. The developed method is based on data exchange ... -
Crystal plasticity finite element simulations of pure bending of aluminium alloy AA7108
Saai, Afaf; Westermann, Ida; Dumoulin, Stephane; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2015)The crystal plasticity finite element method (CP-FEM) is used to investigate the influence of microstructure on the bending behaviour of the heat treatable aluminium alloy AA7108. The study comprises two materials obtained ...
