Genevieve was born in Liverpool, UK where she grew up. She attended the University of Liverpool where she graduated with a first class honours degree in Integrated Engineering in 1999. Her undergraduate project thesis examined the failure modes of thin aluminium panels subjected to pressure pulses. She showed, for the first time, that the failure modes used to classify impulsively loaded beams and plates could also applied to statically and dynamically pressure-loaded metal panels.
She joined the University of Liverpool Impact Research Centre in 1999 and was awarded a PhD in Mechanical Engineering in 2003. Her thesis title was "Failure of corrugated panels and supports under blast loading: experimental, analytical and numerical studies". Her doctoral research was concerned with the performance of corrugated blast walls subjected to gas explosion loading, concentrating on the influence of the connection support in limiting the overall deformation and buckling of the panels. She is currently employed as a senior research assistant at the University of Liverpool, working for Dr Graham Schleyer on various projects concerning structural response to blast and pressure loading. She has been a visiting researcher at the University of Cape Town on three occasions.
Corrugated blast wall panel response (Liverpool)
One of her current research interests is concerned with the performance of corrugated blast walls subjected to gas explosion loading and static pressure loads. Her work focuses on examining on the influence of the connection support, the profile direction, the effect of scaling on the panel response and the buckling modes of the panels. The work, which is an extension of her PhD research, is funded by the UK Health and Safety Executive and the blast wall manufacturers. She is developing analytical and numerical models for use within blast wall design, and performed scaled pressure tests on specimens for future model validation. She has shown that current blast wall design practices lead to overly conservative designs and that ultimate capacities of the blast walls are more than three times the design capacity. The flexibility of connection supports significantly influences the overall behaviour of the blast walls, with a balance needed between conflicting design criteria: the need to minimise force transfer to the primary framework competing with the requirement to limit overall displacements of the walls.
Blast performance of novel lightweight materials (UCT, Liverpool)
The University of Liverpool has developed a range of novel lightweight materials, based on arrangements of metal alloys and thermoplastic based composites. These materials, known as fibre-metal laminates (FMLs), have excellent impact and fatigue properties and have been proposed for use in blast resistant applications. The research work at UCT and the University of Liverpool is investigating their performance under blast loading, and is sponsored by the UK Engineering and Physical Sciences Research Council, the UK Home Office and several industrial project partners. It is investigating the use of blast-resistant materials in street furniture, such as post-boxes and litterbins, as these are possible locations for concealing terrorist bombs. The project comes at a time when there is a growing threat to the general public from terrorist activities. The outcome of this study could lead to a significant reduction in structural damage and personal injuries caused through targeted terrorist bomb attacks in major cities. This new generation of blast-resistant, lightweight, cost-effective fibre-metal laminates is also of value to the aerospace and transport industries, more particularly so as their properties become more widely known.
