Abstract
Fragmentation of the structure of
lattice disorientations at high plastic
strains of metal crystals is studied.
The medium is modelled by the
geometrically nonlinear elastoplastic
Cosserat continuum. The points of the
continuum are identified with
dislocation cells with a frozen crystal
lattice.
