Assessment of the High-frequency Response in Railway Pantograph-Catenary Interaction Based on Numerical Simulation
(Peer reviewed; Journal article, 2020)The numerical model is a well-acknowledged tool to evaluate railway pantograph-catenary interaction performance. The current standard restricts most current simulation tools by a cut-off frequency of 20 Hz. This low-frequency ... -
Assessment of yield and fracture criteria using shear and bending tests
(Journal article; Peer reviewed, 2009)This article deals with the calibration of a fracture criterion that has been implemented in a material model in LS-DYNA. The failure process in thin-walled metallic materials is complex and often due to interaction between ... -
ATLAS of yield surfaces for strongly textured FCC polycrystals
(Journal article; Peer reviewed, 2019)Discrete yield surfaces for several generic texture components, including randomness, found in aluminium alloys have been generated and used to calibrate the yield function Yld2004-18p. It is generally observed that the ... -
Atomic Insights into Hydrogen-Grain Boundary Interactions
(Doctoral theses at NTNU;2023:120, Doctoral thesis, 2023)Derived from the most abundant element in the universe, hydrogen is the smallest element and, at the same time, a clean, mobile, and efficient energy carrier. Nowadays, hydrogen is regarded as the fuel of future and could ... -
Atomistic dewetting mechanics of Wenzel and monostable Cassie–Baxter states
(Journal article, 2018)Water adhesion underlies wettabilities, and thus hydrophobicities, and defines surface properties like self-cleaning, icephobicity and many others. The nanomechanics of water adhesion, especially in the dynamic dewetting ... -
