Continuum theory of dislocation loops

International Journal of Solids and Structures, 1965
Abstract For dislocation loops, the zeroth moment of dislocation strength always vanishes so that the first moment must be defined in order to give a continuum description. A second order tensor is thus introduced to account for the dislocation moment. This physical quantity contains more information than the macroscopic plastic strain.

VACANCIES AND DISLOCATION LOOPS IN GRAPHITE

Applied Physics Letters, 1962
Electron microscope studies were undertaken to determine concentrations and mobilities of vacancies in graphite. Crystals were quenched and annealed to various temperatures. Crystals under strain (some deliberately bent) before heat treatment contained larger numbers of loops while crystals treated under strain- free conditions showed no loops ...
