  • Asymptotic analysis of cold sandwich rolling 

    Cawthorn, Christopher John; Minton, Jeremy; Brambley, Edward James (ElsevierInternational Journal of Mechanical Sciences, 2015-12-22)
    An analytical model for the cold rolling of sandwich sheets is proposed, assuming a rigid-plastic flow rule and Coulomb friction. Asymptotic analysis is used to solve the equations based on the assumptions of small aspect ...

  • Several applications of a model for dense granular flows 

    Cawthorn, Christopher John (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2011-03-15)
    This dissertation describes efforts to evaluate a recently proposed continuum model for the dense flow of dry granular materials (Jop, Forterre & Pouliquen, 2006, Nature, 441, 167-192). The model, based upon a generalisation ...
