Profile

Sam graduated from the University of Sheffield in 2010 with a first-class honours degree in Civil and Structural Engineering, having completed an EPSRC funded research project in the summer before his final year. Sam began his PhD research shortly after graduating, with an interest in the field of Blast Loading on Structures, in particular quantifying the load acting on finite-sized targets and evaluating dynamic response to such loads. In the winter of 2011/12, Sam took a 4 month leave of absence to work as a research assistant at university spin-out company Blastech Ltd., overseeing various high strain rate dynamic experimental tests.

Sam began his post as a Research Associate in April 2014, as part of the EPSRC funded project 'Understanding the role of soil in subsurface explosive events' under supervision from Dr Sam Clarke, and was awarded his PhD shortly afterwards.

He became a Lecturer in Blast and Impact Engineering in January 2016 and currently serves as Outreach and Widening Participation Tutor in the Department of Civil and Structural Engineering.

MatLab script for generating LS-DYNA mesh file for spherical expansion of a blast wave

When modelling explosive detonations and blast wave propagation it is important that material movement is aligned with the elements. If a spherical charge is modelled in a rectangular mesh, an advection error is introduced. By modelling the blast wave in a radially symmetric mesh, this problem can be avoided. This...
