Calibration of the modified Mohr-Coulomb fracture model by use of localization analyses for three tempers of an AA6016 aluminium alloy
(Peer reviewed; Journal article, 2021)This paper presents a novel calibration procedure of the modified Mohr-Coulomb (MMC) fracture model by use of localization analyses and applies it for three tempers of an AA6016 aluminium alloy. The localization analyses ... -
Risk-based Fatigue Design Considering Inspections and Maintenance
(Peer reviewed; Journal article, 2020)The different phases of a structure’s life-cycle are managed by different teams with little interaction. Correspondingly, the optimization of the individual phases is isolated and does not necessarily result in optimal ... -
First principle calculations of pressure dependent yielding in solute strengthened aluminium alloys
(Journal article; Peer reviewed, 2020)The pressure dependence of the yield stress in solute strengthened aluminium alloys is investigated by first principle calculations. The solute elements studied are magnesium, silicon and copper. A fixed boundary cluster ... -
Influence of stress state on plastic flow and ductile fracture of three 6000-series aluminium alloys
(Journal article; Peer reviewed, 2020)In this study, the plastic flow and ductile fracture of three 6000-series aluminium alloys commonly used for crash components in the automotive industry are characterised experimentally and the observations are related to ... -
Covalent coupling regulated thermal conductivity of Poly(vinyl alcohol)/boron nitride composite film based on silane molecular structure
(Peer reviewed; Journal article, 2020)Creating covalent bonds between inorganic fillers and polymer matrix is an effective method to enhance the thermal conductivity (TC) of composite materials, while the detailed mechanism is still not clear. By introducing ... -
Numerical study of hydrogen influence on void growth at low triaxialities considering transient effects
(Peer reviewed; Journal article, 2019)Assuming that hydrogen enhances localised plasticity, as one of the leading mechanisms proposed in the lit- erature, the void growth and coalescence are modified by local softening and ductile failure features depend on ... -
Dynamic Performance of High-Speed Railway Overhead Contact Line Interacting With Pantograph Considering Local Dropper Defect
(Peer reviewed; Journal article, 2020)The local dropper defect is the most common fault in the early service stage of the overhead contact line (OCL) system. The plastic deformation and loose of a dropper may cause the variation of the contact line height, ... -
Vertical vs. Lateral Dynamic Behaviour of Soft Catenaries subject to Regular Loading using Field Measurements
(Journal article, 2020)During the last couple of decades, there has been a steady increase in the development of higher-speed railways. Higher speeds increase the demands on existing railway infrastructure designed for older and different ... -
Durability of cracked SFRC exposed to wet-dry cycles of chlorides and carbon dioxide – Multiscale deterioration phenomena
(Peer reviewed; Journal article, 2020)This paper describes an experimental study that comprised the exposure of cracked SFRC members to wet-dry cycles involving chloride and carbon-dioxide for two years. Results indicate that corrosion of steel fibres occurs ... -
μDIC: An open-source toolkit for digital image correlation
(Peer reviewed; Journal article, 2020)We here present a Digital Image Correlation toolkit, formulated as a Python package. This package aims at providing a complete toolkit for performing DIC analysis on experimental data, performing virtual experiments, as ... -
Uncertainty propagation through a point model for steady-state two-phase pipe flow
(Peer reviewed; Journal article, 2020)Uncertainty propagation is used to quantify the uncertainty in model predictions in the presence of uncertain input variables. In this study, we analyze a steady-state point-model for two-phase gas-liquid flow. We present ... -
Non-destructive Test Methods for Corrosion Detection in Reinforced Concrete Structures
(Peer reviewed; Journal article, 2020)Several inspection methods can be used to assess the corrosion state of steel reinforcement in concrete. Especially for periodical field surveys and monitoring, non-destructive testing (NDT) methods are to be preferred as ... -
When Thermodynamic Properties of Adsorbed Films Depend on Size: Fundamental Theory and Case Study
(Peer reviewed; Journal article, 2020)Small system properties are known to depend on geometric variables in ways that are insignificant for macroscopic systems. Small system considerations are therefore usually added to the conventional description as needed. ... -
Vitamin K2 modulates vitamin D induced mechanical properties of human 3D bone spheroids in vitro
(Peer reviewed; Journal article, 2020)Rotational culture promotes primary human osteoblasts (hOBs) to form three-dimensional (3D) multicellular spheroids with bone tissue-like structure without any scaffolding material. Cell-based bone models enable us to ... -
Self-deicing Electrolyte Hydrogel Surfaces with Pa-level Ice Adhesion and Durable Anti-freezing/frost Performance
(Peer reviewed; Journal article, 2020)Despite the remarkable advances in mitigating ice formation and accretion, however, no engineered anti-icing surfaces today can durably prevent frost formation, droplet freezing and ice accretion in an economical and ... -
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 ... -
Hydroplastic response of a square plate due to impact on calm water
(Peer reviewed; Journal article, 2020)This paper investigates large, plastic deflections of a square plate due to impact on calm water. Most research in the area has examined linear elastic structural responses to such impact, but hydrodynamic responses during ... -
A Surfactant for Enhanced Heavy Oil Recovery in Carbonate Reservoirs in High-Salinity and High-Temperature Conditions
