The development of a novel technique for small ring specimen tensile testing (2018)
Journal Article

The wide scale use of small specimens in routine testing programs could significantly reduce material resource requirements (factors of 10 are easily achievable). This is a major benefit to situations where there is not enough material to manufacture... Read More about The development of a novel technique for small ring specimen tensile testing.

A neural network approach for determining spatial and geometry dependent Green's functions for thermal stress approximation in power plant header components (2018)
Journal Article

The trend in power generation to operate plant with a greater frequency of on/partial/off load conditions creates several concerns for the long term structural integrity of many high temperature components. The Green's function method has been used f...

Effect of post processing on the creep performance of laser powder bed fused Inconel 718 (2018)
Journal Article

In this study, the creep performance of laser powder bed fusion manufactured Inconel 718 specimens is studied in detail and compared with conventional hot-rolled specimens alongside as-built then heat-treated and as-built then hot-isostatic pressed s...

The Prediction of isothermal cyclic plasticity in 7175-T7351 aluminium alloy with particular emphasis on thermal ageing effects (2018)
Journal Article

Rapid thermal ageing has been observed in the literature for certain aerospace aluminium alloys under conditions which are foreseeable in their intended component applications. While several experimental programs have explored this phenomenon in the...

A case study investigation into the effects of spatially dependent convection coefficients on the fatigue response of a power plant header component (2018)
Journal Article

Societal and environmental pressures are forcing thermal power plant operators to deviate greatly from the generation strategies of the past. The application of high frequency start up/shut down/partial load cycles to components that may well be outs... Read More about A case study investigation into the effects of spatially dependent convection coefficients on the fatigue response of a power plant header component.

The influence of shot peening on the fatigue response of Ti-6Al-4V surfaces subject to different machining processes (2018)
Journal Article

Machining processes are known to drastically impact the performance and lifetime of a component subjected to fatigue in service. Therefore, understanding the effect of manufacturing processes on surface integrity is vital to determine their suitabili...

Creep behaviour of inconel 718 processed by laser powder bed fusion (2018)
Journal Article

Additive manufacturing lends itself well to the manufacture of aerospace parts due to the high complexity and small volume of many components found in modern aero engines. By exploiting additive manufacturing design freedoms, enhanced part functional... Read More about Creep behaviour of inconel 718 processed by laser powder bed fusion.
