Aluminium Self-Piercing Rivet's Failure: Testing and Numerical Analyses
Hoang, Nguyen-Hieu; Langseth, Magnus (Peer reviewed; Journal article, 2014)In the present study, the behaviour of aluminium rivets in alloy AA7278-T6 during the riveting process when used to join two aluminium plates was investigated experimentally and numerically. It was observed by Hoang et al. ... -
Elastic and thermodynamic properties of the major clinker phases of Portland cement: Insights from first principles calculations
Mai, Ngoc Lan; Hoang, Nguyen-Hieu; Do, Ha T.; Pilz, Monika; Trinh, Thuat (Peer reviewed; Journal article, 2021)Portland based cement is one of the most popular materials used in the civil and construction applications. Reliable computational methods to provide an insight into the underlying mechanics of the major phases of this ... -
Elucidating the role of tetraethylammonium in the silicate condensation reaction from Ab initio molecular dynamics simulations
Mai, Ngoc Lan; Do, Ha T.; Hoang, Nguyen-Hieu; Nguyen, Anh H.; Tran, Khanh-Quang; Meijer, Evert Jan; Trinh, Thuat (Peer reviewed; Journal article, 2020)The understanding of the formation of silicate oligomers in the initial stage of zeolite synthesis is important. The use of organic structure-directing agents (OSDAs) is known to be a key factor in the formation of different ... -
Novel computational tool for efficient structural analyses of geothermal wells
Hoang, Nguyen-Hieu; Maincon, Philippe Emmanuel; Philippe, David; Coudert, Térence; Bjørset, Arve; Sæther, Sturla (Peer reviewed; Journal article, 2021)In geothermal energy, a huge energy potential lies in hydrothermal reservoirs close to magma where ultra-high temperature fluids (>450 C) can be harnessed. Well casing system needs to be properly designed to ensure its ... -
Structural, Mechanical, Electronic and Thermodynamic Analysis of Calcium Aluminum Silicate Crystalline Phases in Stone Wool Insulation Materials: A first-principles study
Ho, Thi H.; Ha, Do Tuong; Hoang, Nguyen-Hieu; Wilhelmsen, Øivind; Trinh, Thuat (Peer reviewed; Journal article, 2023)Stone wool materials have gained considerable attention due to their effectiveness as thermal and acoustic insulation solutions. The comprehension of crystal structure properties is pivotal in determining the overall ... -
Testing and modelling of butt-welded connections in thin-walled aluminium structures
Hoang, Nguyen-Hieu; Morin, David; Langseth, Magnus (Peer reviewed; Journal article, 2022)The present paper experimentally investigated the mechanical behaviour of butt-welded joints and evaluated suitable numerical approaches for modelling them in thin-walled structures with large shell-based models. Welded ... -
Thermo-mechanical tensile testing of geothermal casing materials
Gruben, Gaute; Dillingh, Bert; Kaldal, Gunnar Skulason; Hoang, Nguyen-Hieu; Wollenweber, Jens; Rørvik, Gisle; Thorbjornsson, Ingólfur Ö; Nyhus, Bård (Peer reviewed; Journal article, 2021)Ultra-high temperature geothermal wells (>450 °C) have a large potential for increased energy yield as compared to conventional high-temperature geothermal wells (200-300 °C), but several research challenges must be resolved ...
