  • Deviatoric response of an armour-grade aluminium alloy 
    Appleby-Thomas, Gareth J.; Hazell, P. J.; Millett, J.; Bourne, Neil K. (AIP American Institute of Physics, 2009-12-31)
    Aluminium alloys such as 5083 H32 are established light-weight armour materials. As such, the shock response of these materials is of great importance. The shear strength of a material under shock loading provides an ...
  • The effects of changing chemistry on the shock response of basic polymers 
    Millett, J.; Brown, E. N.; Gray III, G. T.; Bourne, Neil K.; Wood, D. C.; Appleby-Thomas, Gareth J. (2016-07-11)
    The shock response of four common semicrystalline thermoplastic polymers—polyethylene (PE), polyvinylchloride (PVC), polytetrafluoroethylene (PTFE) and polychlorotrifluoroethylene (PCTFE)—have been studied in terms of their ...
  • Evaluation of the SPH method for the modelling of spall in anisotropic alloys 
    De Vuyst, Tom; Vignjevic, Rade; Bourne, Neil K.; Campbell, James C. (2005-06-27)
    Spall caused by hypervelocity impacts at the lower range of velocities could result in significant damage to spacecraft. A number of polycrystalline alloys, used in spacecraft manufacturing, exhibit a pronounced anisotropy ...
  • Modeling shock waves in orthotropic elastic materials 
    Vignjevic, Rade; Campbell, James C.; Bourne, Neil K.; Djordjevic, Nenad (American Institute of Physics, 2008-08-01)
    A constitutive relationship for modeling of shock wave propagation in orthotropic materials is proposed for nonlinear explicit transient large deformation computer codes (hydrocodes). A procedure for separation of material ...
  • Modelling of impact on a fuel tank using smoothed particle hydrodynamics 
    Vignjevic, Rade; De Vuyst, Tom; Campbell, James C.; Bourne, Neil K. (2005-06-27)
    This paper describes a modelling approach for the simulation of hypervelocity impact on fuel tanks using the Smoothed Particle Hydrodynamics (SPH) method. To determine a suitable particle density, three two-dimensional ...
  • The shock Hugoniot of hydroxy-terminated polybutadiene 
    Meziere, Y.; Akhavan, Jacqueline; Stevens, G. S.; Millett, Jeremy C. F.; Bourne, Neil K. (AIP, 2004-08-04)
    The response of polymers to shock loading is becoming of increasing importance, both as binder systems in plastic-bonded explosives (PBXs) and as structural materials in their own right. In this paper, we report on the ...
