Fatigue damage characterisation of MarBN steel for high temperature flexible operating conditions
(SAGE Publications, 2016-09-10)
This article is concerned with the high temperature low cycle fatigue behaviour of a new nano-strengthened martensiticferritic steel, MarBN. A range of strain-controlled, low cycle fatigue tests are presented on MarBN at ...
Influence of material inhomogeneity on the mechanical response of a tempered martensite steel
(SAGE Publications, 2017-01-13)
Failure in steel weldments operating at high temperatures often occurs in the heat-affected zone adjacent to the weld. Such failures can be a result of material inhomogeneity within the heat-affected zone and in the case ...
Experimental investigation, numerical modelling and multi-objective optimisation of composite wind turbine blades
(Taylor & Francis, 2017-05-24)
Static load and modal testing of two blades from a 15 kW wind turbine is presented. The two blades are made from glass fibre-reinforced polypropylene, one of which has been reinforced with additional carbon fibre plies. ...
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 ...
The effect of ferrite phases on the micromechanical response and crack initiation in the intercritical heat-affected zone of a welded 9Cr martensitic steel
(Wiley, 2018-02-08)
This paper presents a crystal plasticity model to predict the tensile response and crack initiation in a mixed ferrite-martensite material with a low volume fraction of pro-eutectoid ferrite, representative of a welding-induced ...
A physically-based creep damage model for effects of different precipitate types
(Elsevier, 2016-10-13)
The development of a new precipitate coarsening continuum damage mechanics (CDM) model to simulate the multi-precipitate strengthening mechanisms present in 9Cr steels under high temperature creep deformation is presented ...
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 ...
Latent space mapping for generation of object elements with corresponding data annotation
(Elsevier, 2018-10-25)
Deep neural generative models such as Variational Auto-Encoders (VAE) and Generative Adversarial Networks (GAN) give promising results in estimating the data distribution across a range of machine learning fields of ...
A system dynamics approach to increasing ocean literacy
(Frontiers Media, 2019-06-28)
Ocean Literacy (OL) has multiple aspects or dimensions: from knowledge about how the oceans work and our impact on them, to attitudes toward topics such as sustainable fisheries, and our behaviour as consumers, tourists, ...
Iris recognition on consumer devices - challenges and progress
(IEEE, 2015-11-11)
This article outlines various technical, social and ethical challenges in implementing and widely adopting iris recognition technology on consumer devices such as smartphone or tablets. Acquisition of sufficient quality ...
