Physical experimental static testing and structural design optimisation for a composite wind turbine blade
(Elsevier, 2016-12-10)
This study presents experimental testing on a 13 m long glass-fibre epoxy composite wind turbine blade. The results of the test were used to calibrate finite element models. A design optimisation study was then performed ...
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 ...
Rotational moulding of PEEK polymer liners with carbon fibre/PEEK over tape-placement for space cryogenic fuel tanks
(Elsevier, 2017-07-15)
PEEK polymers are investigated as replacement materials for metallic liners in composite overwrapped pressure vessels (COPVs) for fuel tank applications in space. A novel, integrally heated, rotational moulding tool has ...
Permeability of carbon fibre PEEK composites for cryogenic storage tanks of future space launchers
(Elsevier, 2017-06-15)
This work presents an experimental investigation into the permeability of carbon fibre (CF) polyetheretherketone (PEEK) for cryogenic storage tanks for space applications. The effects of cryogenic cycling, manufacturing ...
The effect of inclusions on the high‐temperature low‐cycle fatigue performance of cast MarBN: Experimental characterisation and computational modelling
(Wiley, 2018-06-15)
The presence of inclusions is a known source of crack initiation and component failure in cast materials. In this work, the role of inclusions is investigated via a combined program of high-temperature low-cycle fatigue ...
Influence of microstructural defects and hydrostatic pressure on water absorption in composite materials for tidal energy
(SAGE Publications, 2018-01-06)
The lifespan and economic viability of tidal energy devices are constrained, in part, by the complex degradation of the tidal turbine blade materials due to prolonged immersion in a hostile sub-sea environment. Seawater ...
