(Journal article; Peer reviewed, 2017)Giant magnetostrictive materials are gaining interest in the field of smart material, especially the commercially known Terfenol-D, that is an alloy made out of iron, terbium and dysprosium (Tb0.3Dy0.7Fe1.9). Since these ... -
Fracture assessment of PEEK under static loading by means of the local strain energy density
(Journal article; Peer reviewed, 2017)Polyetheretherketone (PEEK) has gained interest in many industrial applications due to its high strength-to-weight ratio, excellent heat tolerance and high corrosion resistance. Stress concentrators such as notches and ... -
Fracture assessment of polyacrylonitrile nanofiber-reinforced epoxy adhesive
(Journal article, 2018)Electrospun polyacrylonitrile (PAN) nanofibers were incorporated in an epoxy-based adhesive layer to improve the adhesive joint’s mechanical performance. The morphological study of the electrospun PAN nanofibers revealed ... -
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 ... -
Fracture assessment of U-notched PMMA under mixed mode I/II loading conditions by means of local approaches.
(Peer reviewed; Journal article, 2021)The paper investigates the fracture behaviour of U-notched specimens made of polymethylmethacrylate at room temperature under mixed mode loading conditions. The specimens are flat and double notched. The notches bisectors ... -
Fracture assessment of V-notched specimens with end holes made of tungsten-copper functionally graded material under mode I loading
(Journal article; Peer reviewed, 2018)The present research is the first to assess fracture of V-notches with end holes (VO-notches) made of tungsten-copper functionally graded material (W-Cu FGM) under mode I both experimentally and theoretically. W-Cu FGM ... -
Fracture behaviour of notched as-built EBM parts: Characterization and interplay between defects and notch strengthening behaviour
(Journal article, 2018)Additive manufacturing (AM) offers the potential to economically produce customized components with complex geometries. However, the introduction of complex geometry goes hand in hand with the presence of notches. Thus, ... -
Fracture resistance of 3D nano-architected lattice materials
(Journal article, 2022)Exploiting small scale material effects and structural topology, nano-architected lattices represent a recent novel class of mechanical metamaterials, which exhibit unprecedented combination of mechanical properties. ... -
Fracture toughness and hydrogen embrittlement susceptibility on the interface of clad steel pipes with and without a Ni-interlayer
(Journal article, 2017)The objective of the present work has been to study the fracture properties of the interface between clad and base material of two 316 L austenitic stainless steel - X60/X65 carbon steel hot roll bonded clad pipes; with ... -
Fragments Generated during Liquid Hydrogen Tank Explosions
(Peer reviewed; Journal article, 2023)Liquid hydrogen (LH2) may be employed to transport large quantities of pure hydrogen or be stored onboard of ships, airplanes and trains fuelled by hydrogen, thanks to its high density compared to gaseous compressed hydrogen. ... -
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 ... -
Framework for Discussing Sustainability Improvement in Container Ports – a Nordic Case Study
(Doctoral thesis at NTNU;2016:178, Doctoral thesis, 2016)This PhD research project proposes a five-construct framework for discussing how to improve the sustainability performance in Nordic container ports (NCPs). The port of Narvik is used as a representative case study whenever ... -
Framework for Layout Design Supporting Patient Flow in Outpatient Departments
(Master thesis, 2018)In the last decades, there has been an increase in demand for outpatient services, as inpatient treatments are more often done on an outpatient basis. Increase in demand, and long waiting times in the access of outpatient ... -
