A Shock Tube Used to Study the Dynamic Response of Blast-Loaded Plates
(Journal article; Peer reviewed, 2018)This study aims to a better understanding of the performance of a shock tube used to produce blast loading in controlled laboratory environments. Special focus is placed on the influence of the diaphragm failure process ... -
A special notched tensile specimen to determine the flow stress-strain curve of hardening materials without applying the Bridgman correction
(Journal article; Peer reviewed, 2017)Structural integrity assessment of weldments requires the input of flow stress-strain curve of each individual material zone. To cope with these challenges, a cylindrical cross weld tensile specimen with a notch located ... -
A study of the influence of precipitate free zones on the strain localization and failure of the aluminium alloy AA7075-T651
(Journal article; Peer reviewed, 2015)Age-hardened aluminium alloys have various degrees of precipitate-free zones (PFZs) along grain boundaries (GBs). The PFZs are weak zones and their existence promotes combined transgranular and intergranular fracture, thus ... -
A thermo-elasto-viscoplastic constitutive model for polymers
(Journal article; Peer reviewed, 2018)In this study, a thermo-elasto-viscoplastic model is developed for a low density cross-linked polyethylene (XLPE) in an attempt to describe the combined effects of temperature and strain rate on the stress-strain response ... -
A through-thickness damage regularisation scheme for shell elements subjected to severe bending and membrane deformations
(Journal article; Peer reviewed, 2018)This research work proposes and validates a damage regularisation model for shell elements used in large-scale simulations. The model evaluates the ratio of bending to membrane loading in the elements based on the ... -
A two-stage numerical analysis approach for the assessment of the settlement response of the pre-damaged historic Hoca Pasha Mosque
(Journal article; Peer reviewed, 2019)The current article presents a case study of the settlement response of the historic Hoca Pasha Mosque that involves uncertainties arising from the complex excavation activities, soil properties, building materials, and ... -
A uniform hydrogen degradation law for high strength steels
(Journal article; Peer reviewed, 2016)The degrading effect of hydrogen on high strength steels is well recognized. The hydrogen degradation is dependent not only on hydrogen content, but also on geometric constraints or equivalently, level of stress triaxiality, ... -
Adiponectin reduces bone stiffness; verified in a 3D artificial human bone model in vitro
(Journal article; Peer reviewed, 2018)Primary human osteoblasts and osteoclasts incubated in a rotating coculture system without any scaffolding material, form bone-like tissue that may be used to evaluate effects of various compounds on mechanical strength. ... -
Aerogel-Incorporated Concrete: An Experimental Study
(Journal article; Peer reviewed, 2014)Lightweight concrete can be prepared by replacing the normal aggregate of concrete, either partly or totally, with lightweight materials. In this work, by incorporating silica aerogel particles into concrete matrix, we ... -
ALE-VMS methods for wind-resistant design of long-span bridges
(Peer reviewed; Journal article, 2019)For unsteady aerodynamics, the Arbitrary Lagrangian-Eulerian Variational Multi-Scale (ALE-VMS) formulation for incompressible flows has proven an accurate and powerful method. In this paper we present an overview of some ... -
Alkali Aggregate Reactions (AAR) in Norway: Thin section analysis and expansion measurements from a dam and a bridge
(Peer reviewed; Journal article, 1992)Two concrete structures with AAR have been investigated. The structures are a dam and a bridge, both approximately 30 years old. Both structures have a characteristic crack pattern on the surface of the concrete. Thin ... -
Alkali-silica reaction (ASR)-performance testing: Influence of specimen pre-treatment, exposure conditions and prism size on alkali leaching and prism expansion
(Journal article; Peer reviewed, 2013)Whether or not concrete prism tests developed for assessment of alkali–silica reactivity of aggregates might be suitable for general ASR performance testing of concrete has been evaluated. This paper discusses how variations ... -
Alkali–silica reaction (ASR)—performance testing: Influence of specimen pre-treatment, exposure conditions and prism size on concrete porosity, moisture state and transport properties

Aluminium Self-Piercing Rivet's Failure: Testing and Numerical Analyses
(Journal article; Peer reviewed, 2014)In the present study, the behaviour of aluminium rivets in alloy AA7278-T6 during the riveting process when used to join two aluminium plates was investigated experimentally and numerically. It was observed by Hoang et al. ... -
Aluminum foam-filled extrusions subjected to oblique loading: experimental and numerical study
(Journal article; Peer reviewed, 2004)The behavior of empty and foam-filled square thin-walled aluminum columns in alloy AA6060 subjected to quasi-static oblique loading was examined. Previous studies have shown that by introducing a load angle, the energy ... -
An experimental and numerical study on the volume change of particle-filled elastomers in various loading modes
