  • 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 dynamic damage and failure in aluminium alloys 
    Vignjevic, Rade; Djordjevic, Nenad; Campbell, James C.; Panov, Vili (Elsevier Science B.V., Amsterdam., 2012-11-30)
    A physically based damage and failure model, applicable to orthotropic metals is proposed in this paper. To account for the physical mechanisms of failure, the concept of thermally activated damage initially proposed by ...
  • 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 ...
  • Modelling of liquid metal flow and oxide film defects in filling of aluminium alloy castings 
    Dai, Xiaojun J.; Jolly, Mark R.; Yang, X; Campbell, James C. (2012-12-31)
    The liquid metal flow behaviours in different runner system designs have important effects on the mechanical strength of aluminium alloy castings. In this paper, a new model has been developed which is a two-dimensional ...
  • Non-linear idealisation error analysis of a metallic stiffened panel loaded in compression 
    Campbell, James C.; Hetey, Laszlo; Vignjevic, Rade (Elsevier Science B.V., Amsterdam., 2012-05-31)
    The SAFESA procedure is an idealisation error control process developed for linear static finite element (FE) analysis. This paper investigates the application of this process to non-linear FE in order to provide an ...
  • Numerical simulation of high velocity impacts on thin metallic targets I and II 
    Vignjevic, Rade; Campbell, James C.; Lepage, Séverine (2004-12-18)
    Spacecraft encounter various impact phenomena in space, among which orbital debris impacts are of most concern. These impacts occur at a wide range of velocities. Impact velocities from a few hundreds m/s to one km/s are ...
  • A numerical study on the influence of internal corrugated reinforcements on the biaxial bending collapse of thin-walled beams 
    Vignjevic, Rade; Liang, Ce; Hughes, Kevin; Brown, Jason C.; De Vuyst, Tom; Djordjevic, Nenad; Campbell, James C. (Elsevier, 2019-07-25)
    The Heat Treatment Forming and in-die Quench (HFQ) process allows for manufacturing of more complex geometries from Aluminium sheets than ever before, which can be exploited in lightweight automotive and aerospace structures. ...
  • Simulating structural response to water impact 
    Campbell, James C.; Vignjevic, Rade (Elsevier Science B.V., Amsterdam., 2012-11-30)
    Structural response to water impact is important for several areas, including the aerospace and marine industries. Aircraft must be designed to cope with ditching and offshore structures are subject to extreme wave impact ...
