A review of the integrity of metallic vehicle armour to projectile attack
(SAGE Publications, 2018-02-28)
This article presents a review of engineering and design aspects relevant to the mechanical and structural integrity of military vehicular armour, including materials-related technologies. Theoretical, experimental and ...
Validation of the multi-objective structural optimisation of a composite wind turbine blade
(Elsevier, 2018-08-01)
Structural optimisation of a wind turbine blade is presented in this work. The optimisation was performed using a multi-objective genetic algorithm and finite element modelling to determine the optimal structural design ...
A two and three-dimensional CFD investigation into performance prediction and wake characterisation of a vertical axis turbine
(AIP Publishing, 2018-05-24)
The emergence of tidal energy as a key renewable energy source requires the development of computational design models for accurate prediction of turbine performance and wake effects whilst also being computationally ...
A strain-gradient, crystal plasticity model for microstructure-sensitive fretting crack initiation in ferritic-pearlitic steel for flexible marine risers
(Elsevier, 2018-02-03)
A three-dimensional, strain-gradient, crystal plasticity methodology is presented for prediction of microstructure-sensitive length-scale effects in crack initiation, under fatigue and fretting fatigue conditions, for a ...
An efficient computational framework for hydrofoil characterisation and tidal turbine design
(Elsevier, 2018-11-13)
Blade element momentum (BEM) modelling offers a computationally inexpensive means of analysing turbine performance. Lift and drag coefficient data-sets specific to the operating conditions of the turbine must be input into ...
Fatigue life of pitch- and stall-regulated composite tidal turbine blades
(Elsevier, 2018-02-28)
Tidal turbine blades are subject to harsh loading and environmental conditions, including large thrust and torsional loadings, relative to wind turbine blades, due to the high density of seawater, among other factors. The ...
Experimental characterisation and computational modelling for cyclic elastic-plastic constitutive behaviour and fatigue damage of X100Q for steel catenary risers
(Elsevier, 2018-06-21)
New higher strength steels are required for deep and ultra-deepwater steel catenary risers (SCRs). In this work, the cyclic elastic-plastic-damage behaviour of X100Q, a candidate next-generation SCR material is experimentally ...
An experimental study of a flow-accelerating hydrokinetic device
(SAGE Publications, 2018-05-01)
Tidal energy researchers and developers use experimental testing of scaled devices as a method of evaluating device performance. Much of the focus to date has been on horizontal axis turbines. This study is focused on a ...
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 ...
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 ...
