Micro-mechanical modelling of fretting fatigue crack initiation and wear in Ti-6Al-4V
(Elsevier ScienceDirect, 2013-05-02)
A micro-mechanical modelling methodology is presented for predicting fretting fatigue crack nucleation in Ti–6Al–4V. The methodology is based on a combination of (i) a unit cell crystal plasticity model of Ti–6Al–4V, (ii) ...
Design of composite tidal turbine blades
(2013-02-24)
Tidal turbine blades are subjected to significant thrust and torsional loadings due to the high density ofthe seawater in which they operate. These thrust loadings lead to high bending moments at the bladeroot, which can ...
An XFEM-Based Methodology for Fatigue Delamination and Permeability in Composites
(2014)
Carbon fibre reinforced polymers (CFRP) are one of the prospective material families being investigated for use in the fuel tanks of future reusable space launch vehicles (RSLVs). The extreme thermo-mechanical loading that ...
Characterization of renewable reductants and charcoal-based pellets for the use in ferroalloy industries
(Elsevier, 2018-11-05)
This study investigates the effect of high-temperature pyrolysis and post-treatment processes on spruce and oak charcoal yields and CO2 reactivity in a slow pyrolysis reactor. Post-treatment processes such as co-pyrolysis ...
Comparison of high temperature chars of wheat straw and rice husk with respect to chemistry, morphology and reactivity
(Elsevier, 2016-03-02)
Fast pyrolysis of wheat straw and rice husk was carried out in an entrained flow reactor at high-temperatures (1000–1500) °C. The collected char was analyzed using X-ray diffractometry, N2-adsorption, scanning electron ...
Damage characterisation of cryogenically cycled carbon fibre/PEEK laminates
(Elsevier ScienceDirect, 2014-08-14)
A unique insight into damage formation in CF/PEEK laminates before, during and after cryogenic cycling, using optical microscopy and 3D X-ray computed tomography (CT), is presented. Thicker laminates were found to exhibit ...
High temperature, low cycle fatigue characterisation of P91 weld and heat affected zone material
(American Society of Mechanical Engineers, 2014-01-08)
The high temperature low cycle fatigue behavior of P91 weld metal (WM) and weld joints (cross-weld) is presented. Strain-controlled tests have been carried out at 400 °C and 500 °C. The cyclic behavior of the weld material ...
Characterization and reactivity of soot from fast pyrolysis of lignocellulosic compounds and monolignols
(Elsevier, 2018-02-06)
This study presents the effect of lignocellulosic compounds and monolignols on the yield, nanostructure and reactivity of soot generated at 1250 C in a drop tube furnace. The structure of soot was characterized by electron ...
Computational study on the effect of contact geometry on fretting behaviour
(Elsevier ScienceDirect, 2011-07-23)
A key challenge in the design of engineering couplings and contacting components relates to the development of an understanding of the comparative performance of contrasting contact geometries for a given application, ...
