Dislocation core properties of \beta-tin: A first-principles study
, 2017 Dislocation core properties of tin (\beta-Sn) were investigated using the semi-discrete variational Peierls-Nabarro model (SVPN). The SVPN model, which connects the continuum elasticity treatment of the long-range strain field around a dislocation with ...

The gauge theory of dislocations: a nonuniformly moving screw dislocation
, 2010 We investigate the nonuniform motion of a straight screw dislocation in infinite media in the framework of the translational gauge theory of dislocations. The equations of motion are derived for an arbitrary moving screw dislocation.

Finite element models of wedge disclination
Nihon Kikai Gakkai ronbunshu, 2014 Numerical analysis of the elastic stress field around a wedge-type disclination is first presented. Disclinations are lattice defects accompanied by multi-valued displacement field. The discontinuity in displacement is dealt with finite element method in

Processes of Dis–location and Re–location of Knowledge and Power
Kervan. International Journal of Afro-Asiatic Studies, 2016 Historical analysis of domination patterns identifies phases of ongoing dialectics between rich and poor world areas, claiming instances of self-determination and empowerment in international programs of cooperation.

Dislocation nucleation and vacancy formation during high-speed deformation of fcc metals
, 2001 Recently, a dislocation free deformation mechanism was proposed by Kiritani et al., based on a series of experiments where thin foils of fcc metals were deformed at very high strain rates.

Predicting dislocation climb: Classical modeling versus atomistic simulations [PDF]
, 2011 The classical modeling of dislocation climb based on a continuous description of vacancy diffusion is compared to recent atomistic simulations of dislocation climb in body-centered cubic iron under vacancy supersaturation [Phys. Rev. Lett.
