Andrew graduated from the University of Sheffield with an MEng (Hons) degree in Structural Engineering & Architecture in 2012. He then joined the Geotechnical Engineering Group and completed his PhD studying strain rate effects in soils in 2016.

During his doctorate studies Andrew spent a number of periods working with the university spin-out company Blastech. He is now a Research Associate in the Blast and Impact Dynamics research group, working on the EPSRC-funded Mechanisms and Characterisation of Explosions (MaCE) project.

Much of Andrew’s research to date has focused on the effect of strain rate on material behaviour. How quickly a load is applied to a material (the strain rate) can greatly affect properties such as stiffness and strength, and this effect is particularly important when investigating very rapid loadings such as explosions.

His research on strain rate effects in soils is vital for understanding how to defend against buried explosive devices such as mines and IEDs, and has aided the development of soil-filled structures to protect people and infrastructure from ballistic threats.

The destructive nature of explosions makes them inherently difficult to measure and characterise, but a full understanding of their effects is vital to improve the life-saving ability of next-generation blast protection systems.

Andrew’s current research on the MaCE project aims to develop a comprehensive model of the loading from explosions by investigating the pressure, temperature and chemical reactions in the blast wave as it develops.
