Existence and stability of a screw dislocation under anti-plane deformation [PDF]
, 2014 We formulate a variational model for a geometrically necessary screw dislocation in an anti-plane lattice model at zero temperature. Invariance of the energy functional under lattice symmetries renders the problem non-coercive.

Influence of the Rake Angle on Nanocutting of Fe Single Crystals: A Molecular-Dynamics Study
Crystals, 2020 Using molecular dynamics simulation, we study the cutting of an Fe single crystal using tools with various rake angles α . We focus on the (110)[001] cut system, since here, the crystal plasticity is governed by a simple mechanism for not too ...

Phase singularities in isotropic random waves [PDF]
, 2000 The singularities of complex scalar waves are their zeros; these are dislocation lines in space, or points in the plane. For waves in space, and waves in the plane (propagating in two dimensions, or sections of waves propagating in three), we calculate ...
