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, ... -
Adhesion strength of tetrahydrofuran hydrates is dictated by substrate stiffness
(Peer reviewed; Journal article, 2023)Understanding the hydrate adhesion is important to tackling hydrate accretion in petro-pipelines. Herein, the relationship between the Tetrahydrofuran (THF) hydrate adhesion strength (AS) and surface stiffness on elastic ... -
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. ... -
Aerodynamic damping models for vortex-induced vibration of a rectangular 4: 1 cylinder: Comparison of modeling schemes
(Peer reviewed; Journal article, 2020)Accurate modeling of vortex-induced force acting on a structure is of great significance to precisely evaluate its vortex-induced vibration (VIV). This paper systematically compares the capabilities of five aerodynamic ... -
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 ... -
Ag Nanoparticle-Coated Polystyrene Microspheres for Electromagnetic Interference Shielding Films with Low Metal Content
(Peer reviewed; Journal article, 2022)The fabrication of thin composite films incorporating metal-based fillers with a delicate structure to achieve high electromagnetic interference shielding effectiveness (EMI SE) at low metal content remains a great challenge. ... -
Al uptake in calcium silicate hydrate and the effect of alkali hydroxide
(Peer reviewed; Journal article, 2022)The effect of Al and of pH on the structure of calcium silicate hydrate (C-S-H), the most important hydration product in Portland and blended cement, was studied at Ca/Si ~1.0. The presence of Al led to higher amounts of ... -
