  • Creep at very low rates
    Thumbnail
    Author: Nabarro, FRN Date: Feb 2002 The creep rate in a land-based power station must be less than 10(-11) s(-1). At these low rates of deformation the transport of matter occurs by the migration of vacancies rather than by the glide of dislocations. A quantitative understanding ... Read more
  • Fifty-year study of the Peierls-Nabarro stress
    Thumbnail
    Author: Nabarro, FRN Date: 30 Aug 1997 The origin of the Peierls model and its relation to that of Frenkel and Kontorova are described. Within this model there are three essentially different formulae for the stress required to move a dislocation rigidly through a perfect lattice, ... Read more
  • One-dimensional models of thermal activation under shear stress
    Thumbnail
    Author: Nabarro, FRN Date: 2003 The analysis of thermal activation under shear stress in three- and even two-dimensional models presents unresolved problems. The analysis of one-dimensional models presented here may illuminate the study of more realistic models. For the ... Read more
