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 ... -
Additive manufacture of superduplex stainless steel using WAAM
(Journal article; Peer reviewed, 2018)Superduplex stainless steels have been used in the oil and gas industry for a couple of decades due to the combination of excellent mechanical properties and corrosion resistance. The present investigation addresses the ... -
An investigation of outlier detection procedures for CMM measurement data
(Journal article; Peer reviewed, 2018)The paper analyses methods for outlier detection in dimensional measurement. The cross sections of an internal cylinder were inspected by CMM (coordinate measuring machine), and received data sets were employed for further ... -
Experimental and numerical investigation of strain distribution of notched lead fatigue test specimen
(Journal article; Peer reviewed, 2018)The work here presented focuses on the test methodology related to effect of stress concentrators in strain controlled structures. Cable sheathing as used in subsea power cables are investigated by cyclic fatigue testing, ... -
Fatigue assessment of semi-circular notched specimens produced by Laser Engineered Net Shaping method
(Journal article; Peer reviewed, 2018)As a primary failure mechanism, fatigue failure of additively manufactured metallic parts has attracted considerable attention in both aerospace and biomedical applications. According to some specific design requirements, ... -
Fatigue investigation of complex weldments by the means of the local strain energy density approach
(Journal article; Peer reviewed, 2018)The paper investigates the use of an energetic approach based on the strain energy density failure criteria to predict the fatigue life of welded joints in aluminum alloy. The cited criterion has already been proved valid ... -
High cycle fatigue life estimation of AlSi10Mg processed by laser powder bed fusion
(Journal article; Peer reviewed, 2018)Fatigue life is known to be dependent on the surface properties of the material. Surface roughness provokes local stress concentration and cause crack initiation even at minute cyclic loads. In laser powder bed fusion, the ... -
Hydrogen-assisted fatigue crack growth in ferritic steels – a fractographic study
(Journal article; Peer reviewed, 2018)Fatigue crack growth (FCG) behavior of a Fe-3wt.%Si ferritic alloy under different environmental conditions using in-situ electrochemical (cathodic) hydrogen (H) charging has been investigated. Three frequencies have been ... -
Local strain energy based fatigue assessment of cruciform welded joints: experimental data analysis and influence of hot-dip galvanization
(Journal article; Peer reviewed, 2018)Performing the fatigue assessment of a welded joint using the Notch Stress Intensity Factors [1] presents two major challenges. The first is the necessity of a precise reconstruction of the stress field around the notch ... -
Robust estimation of optimal sample size for CMM measurements with statistical tolerance limits
(Journal article; Peer reviewed, 2018)The paper proposes the kernel probability density function approach to estimate the distribution of measurements on a part which is measured in a coordinate measuring machine (CMM). The study is based on the experimental ... -
Using the Hybrid Metal Extrusion & Bonding (HYB) Process for Butt Welding of 4 mm Plates of AA6082-T6
(Journal article; Peer reviewed, 2018)Hybrid Metal Extrusion & Bonding is a new solid state joining technique developed for aluminium alloys. By the use of filler material addition and plastic deformation sound joints can be produced at operational temperatures ...
