Profile

Andrew joined the group as a PhD student after graduating from The University of Sheffield with an MEng (Hons) in Structural Engineering and Architecture.

He researches how the properties of soils can be used to protect people from the effects of explosions and high-velocity fragments, including

  • High-pressure characterisation of geomaterials
  • Strain-rate effects in soils
  • Moisture content variation in gabion structures

(2016). Effects of strain rate and moisture content on the behaviour of sand under one-dimensional compression. Experimental Mechanics, 56 (9), pp. 1625-1639. (Full Text), Abstract: The influence of strain rate and moisture content on the behaviour of a quartz sand was assessed using high-pressure quasi-static (0.001 /s) and high-strain-rate (1000 /s) experiments under uniaxial strain. Quasi-static compression to axial stresses of 800 MPa was carried out alongside split...

(2015). Finite element modelling of split-Hopkinson pressure bar experiments on sand. (Full Text), Abstract: Finite element modelling of confined split Hopkinson pressure bar (SHPB) tests on dry quartz sand have been carried out using LS-DYNA to assess the suitability of models *MAT_SOIL_AND_FOAM and *MAT_MOHR_COULOMB for simulating high-pressure transient events in soils. Both models were defined using...
