A review of additive manufacturing of cermets
(Peer reviewed; Journal article, 2020)Cermets are a category of materials including ceramic and metallic phases, which possess the combined properties of both phases. Over the last few decades, numerous conventional processes such as powder metallurgy techinques ... -
The effects of microporosity in struts of gyroid lattice structures produced by laser powder bed fusion
(Peer reviewed; Journal article, 2020)Additive manufacturing by laser powder bed fusion allows the production of complex parts including lattice structures in popular metal alloys such as Ti6Al4V. Lattice structures are a class of meta-materials which hold ... -
Volume Free Strain Energy Density Method for Applications to Blunt V-Notches
(Peer reviewed; Journal article, 2020)This work investigates the application of the strain energy density method to rounded V-notches under mode I loading conditions and to components without stress concentrators through finite element models that do not involve ... -
Porosity Inducing Process Parameters in Selective Laser Melted AlSi10Mg Aluminium Alloy
(Peer reviewed; Journal article, 2020)Additive manufacturing techniques are known for the unrivalled geometric freedom they offer to designers. It is one of the mainstays of “metal 3D-printing”, compared to casting, which, in contrast, implies more restrictions ... -
Brittle fracture prediction of key-hole notched specimens by means of J-integral expression
(Peer reviewed; Journal article, 2020)The main goal of the present research is to check if J-integral criterion is capable of predicting the onset of brittle fracture in key-hole notched isostatic poly-granular graphite plates. In this way, this article provides ... -
Fracture assessment of U-notched graphite specimens by means of cohesive zone model
(Peer reviewed; Journal article, 2020)Various types of graphite have gained interest in many industrial applications due to their high strength and excellent heat tolerance. However, due to the brittle nature of this material, presence of stress concentrators ... -
Validation of the average strain energy density criterion for additively manufactured notched polylactide acid specimens
(Peer reviewed; Journal article, 2020)The applicability of the Averaged Strain Energy Density (ASED) criterion [1] to predict the failure of notched Polylactide Acid (PLA) specimens fabricated by Fused Deposition Modeling (FDM) is validated by means of ... -
Meta-Learning Potential to Assess Uncertainties in Dynamic Risk Management
(Chapter, 2020)Meta-learning studies how learning systems can increase in efficiency through experience. Its purpose is to understand how learning itself can become flexible according to the tasks or contexts under study. These properties ... -
Integration Between Occupational and Process Safety: Existing Approaches and Challenges for an Enhanced Framework
(Peer reviewed; Journal article, 2020)Occupational safety is traditionally managed distinctly from process safety. The former puts the emphasis on high frequency and low consequence incidents, and refers to hazards that could provoke human consequences. In ... -
FRAM Approach for Barrier Management in Offshore Drilling
(Chapter, 2020)Accident investigations in offshore oil and gas industry indicate that inadequate barrier management has been one of the main causes of many offshore accidents. Event trees commonly have been used for safety barrier risk ... -
Prognostics and Maintenance Optimization in Bridge Management
(Chapter, 2019)This paper has been written in collaboration with the Norwegian Public Roads Administration (NPRA). In Norway, bridges are a vital part of the transportation infrastructure. With more than 18,000 road bridges across the ... -
Leveraging Model Based Definition and STEP AP242 in Task Specification for Robotic Assembly
(Peer reviewed; Journal article, 2020)This article explores using aspects of STEP AP242 for constraint-based robot programming for assembly operations. Industry 4.0 envisions smart, connected factories where all the operations are connected by an unbroken ... -
A New Fault Identification Method Based on Combined Reconstruction Contribution Plot and Structured Residual
(Chapter, 2020)The existing contribution plot-based reconstruction fault identification methods suffer from low identification accuracy and serious trailing effect. In this paper, a new fault identification method is proposed based on a ... -
Collaborative Fault Diagnosis Decision Fusion Algorithm Based on Improved DS Evidence Theory
(Chapter, 2020)DS evidence theory has in obtaining a correct diagnosis when confronted with highly conflicting evidence, a collaborative fault diagnosis decision fusion algorithm based on an improved version of DS evidence theory is ... -
The complementary effect of lean manufacturing and digitalisation on operational performance
(Peer reviewed; Journal article, 2020)The most recent trend manufacturers have embraced to seek operational performance improvements is the use of a wide range of digital technologies typically associated with Industry 4.0. However, few studies have investigated ... -
Planning Environments of Hospital Laboratories: An Exploratory Study
(Chapter, 2020)Hospital laboratories are facing challenges of increasing demand and limited budgets. Planning and control can improve resource utilization, reduce work-in-progress and shorten throughput times, but to achieve such benefits, ... -
Impurity removal from Si by Si-Ca-Mg ternary alloying-leaching system
(Peer reviewed; Journal article, 2020)In this work, Si-Ca-Mg alloys were made with different compositions and solidification conditions to investigate the impurity segregation and separation performance from Si, especially for the crucial P impurity at several ... -
Material Screening
(SINTEF Rapport;, Research report, 2020)The report summarizes the main results from the slow strain rate tensile testing campaign performed within the framework of the HyLINE project. The metallurgical characterization of the pipe, in terms of base metals (BM), ... -
Analyzing the factors affecting engineering change implementation performance in the engineer-to-order production environment: case studies from a Norwegian shipbuilding group
(Peer reviewed; Journal article, 2020)Engineering changes (ECs) are unavoidable in the engineer-to-order (ETO) environment. ECs improve products and bring additional profit to ETO companies if effectively negotiated and implemented. Despite the abundant relevant ... -
