Interpretation of pipe-jacking and lubrication records for drives in silty soil
(Elsevier, 2019-04-22)
In recent years, there has been an increased resort to microtunnelling/pipe-jacking as a means of constructing underground conduits (for water, sewage, gas, and other utilities) to avoid on-street disruption in urban areas. ...
A physically-based high temperature yield strength model for 9Cr steels
(Elsevier, 2018-05-24)
The strength of 9Cr steels, which is controlled by chemical composition and microstructure, evolves significantly under high temperature loading. This paper presents a temperature-independent, physically-based model for ...
A model for surface tension in the meshless finite volume particle method without spurious velocity
(Elsevier, 2018-11-22)
A surface tension model has been developed in the finite volume particle method (FVPM). FVPM is a conservative, consistent, meshless particle method that incorporates properties of both smoothed particle hydrodynamics and ...
Pile groups under axial loading: an appraisal of simplified non-linear prediction models
(Thomas Telford (ICE Publishing), 2019-06-12)
The settlement behaviour of vertically loaded pile groups has been the subject of an extensive body of research over the past two decades. In particular, this work has identified the over-conservatism associated with ...
Application of a staged automated calibration methodology to a partially-retrofitted university building energy model
(Elsevier, 2019-07-10)
Deep-retrofit planning for existing buildings demands high accuracy in energy modelling prediction that minimises the gap between actual and simulated scenarios. A large set of interacting variables and uncertainties in ...
Effect of pre-corrosion on damage evolution and crack propagation in aluminum alloy 7050-T7651
(Wiley, 2018-05-16)
This paper investigates the effects of pre-corrosion on the tensile behavior of aluminum alloy 7050-T7651. A combined experimental approach involving digital image correlation, scanning electron microscopy, and tensile ...
A multi-scale crystal plasticity model for cyclic plasticity and low-cycle fatigue in a precipitate-strengthened steel at elevated temperature
(Elsevier, 2016-12-24)
In this paper, a multi-scale crystal plasticity model is presented for cyclic plasticity and low-cycle fatigue in a tempered martensite ferritic steel at elevated temperature. The model explicitly represents the geometry ...
A living thick nanofibrous implant bifunctionalized with active growth factor and stem cells for bone regeneration
(Dove Medical Press, 2015-02-04)
New-generation implants focus on robust, durable, and rapid tissue regeneration to shorten recovery times and decrease risks of postoperative complications for patients. Herein, we describe a new-generation thick nanofibrous ...
High-resolution measurements of leakage flow inside the hinge of a large-scale bileaflet mechanical heart valve hinge model
(Springer, 2019-06-24)
Purpose It is believed that non-physiological leakage flow through hinge gaps during diastole contributes to thrombus formation in Bileaflet Mechanical Heart Valves (BMHVs). Because of the small scale and difficulty of ...
A combined wear-fatigue design methodology for fretting in the pressure armour layer of flexible marine risers
(Elsevier, 2016-10-20)
This paper presents a combined experimental and computational methodology for fretting wear-fatigue prediction of pressure armour wire in flexible marine risers. Fretting wear, friction and fatigue parameters of pressure ...
