3D-Focused ion beam tomography and quantitative porosity evaluation of ZrO2-SiO2 composite coating; amorphous SiO2 as a porosity tailoring agent
(Peer reviewed; Journal article, 2020)The current study is focused on refining effect of amorphous SiO2 on porosity and interlayer formation of sintered ZrO2-SiO2 composite coatings produced on anodic oxidized 316L substrate. The SiO2 improved particle interaction ... -
40CrMoV13.9 notched specimens under multiaxial fatigue: An overview of recent results
(Journal article; Peer reviewed, 2017)The multiaxial fatigue strength of circumferentially V-notched and semicircular notched specimens made of 40CrMoV13.9 has been investigated in this paper. The multiaxial load were applied using combined tension and torsion ... -
A Blended Learning Approach to Teaching Project Management: A Model for Active Participation and Involvement: Insights from Norway
(Journal article; Peer reviewed, 2015)The paper demonstrates and evaluates the effectiveness of a blended learning approach to create a meaningful learning environment. We use the term blended learning approach in this paper to refer to the use of multiple or ... -
A comparative study between traditional topology optimization and lattice optimization for additive manufacturing
(Journal article; Peer reviewed, 2019)Topology optimization (TO) aids designers to come up with new ideas that would be impossible to be designed without this technology. However, the optimized results are usually characterized by high geometric complexity, ... -
A Comparative Tribocorrosion Study of Additive Manufactured and Wrought 316L Stainless Steel in Simulated Body Fluids
(Journal article; Peer reviewed, 2018)In this study, the corrosion and tribocorrosion behavior of additive manufactured (AM) 316L is investigated and compared to wrought 316L. The experiments were performed in both a 0.9 wt% NaCl solution and a simulated body ... -
A comparison between numerical and approximate methods for rapid calculation of NSIFs
(Journal article; Peer reviewed, 2019)To more rapidly predicting the integrity of components weakened by sharp notches, notch stress intensity factors (NSIFs) are usually evaluated. Many methods have been proposed evaluating NSIFs, ranging from the stress ... -
A Comparison of Hazards and Efficiencies of Conventional and Adaptive Control Algorithms Using Systems-Theoretic Process Analysis
(Journal article; Peer reviewed, 2019)Control systems are an important and increasingly complex part of most industrial and non-industrial systems. As such, identifying and handling associated risks is increasingly important. Systems- Theoretic Process Analysis ... -
A comprehensive numerical investigation of the impact behaviour of an offshore wind turbine blade due to impact loads during installation
(Journal article, 2019)For installing offshore wind turbines into deep waters, use of floating crane vessels is essential. One of the major challenges is their sensitivity to wave-induced vessel and crane tip motions, which can cause the impact ... -
A computational approach to expose conversation dynamics in engineering design activities
(Journal article, 2017)In this paper, we apply a computational approach to expose conversation dynamics in design conversations. We apply this approach to a case study comprising of two sessions, with 300 speaker turns respectively. The resulting ... -
A coupled diffusion and cohesive zone modelling approach for numerically assessing hydrogen embrittlement of steel structures
(Journal article; Peer reviewed, 2017)Simulation of hydrogen embrittlement requires a coupled approach; on one side, the models describing hydrogen transport must account for local mechanical fields, while on the other side, the effect of hydrogen on the ... -
A Curvature-Based Descriptor for Point Cloud Alignment Using Conformal Geometric Algebra
(Journal article; Peer reviewed, 2018)This paper presents a descriptor for course alignment of point clouds using conformal geometric algebra. The method is based on selecting keypoints depending on shape factors to identify distinct features of the object ... -
