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 ... -
Micromechanical Modelling of Strain Localization and Fracture in Aluminium
Martinsen, Vegard (Master thesis, 2012)Aluminium is often treated as a homogeneous material. However, when investigated on a microscopic scale, a granular structure is observed. The mechanical properties of the constituents, together with the distribution of ... -
Microstructure-based modelling and simulation of the mechanical behaviour of dual-phase steels
Pettersen, Erlend Eksaa (Master thesis, 2017)This project is concerned with the behaviour and modelling techniques of ferrite-martensite dual-phase steels, with the intention of creating a general relation between the microstructural properties of the materials and ... -
A numerical study on the effects of DP steel microstructure on the yield locus and the stress–strain response under strain path change
Saai, Afaf; Hopperstad, Odd Sture; Fritz, Jenny; Larsson, Joachim (Journal article; Peer reviewed, 2023)The mechanical response of dual phase (DP) steel exhibits a complex dependence on the microstructure. The chemical composition and microstructure characteristics of the phases have significant effects on the contrast between ...
