Elementary atomistic mechanism of crystal plasticity

The simulation of loaded crystal behavior under relaxation is carried out. Typical local structural distortions named protodefects, which give rise to conventional lattice defects, are discovered. The dynamics of atomic displacements that govern protodefect nucleation is studied in detail. A local e...

Description
Summary:The simulation of loaded crystal behavior under relaxation is carried out. Typical local structural distortions named protodefects, which give rise to conventional lattice defects, are discovered. The dynamics of atomic displacements that govern protodefect nucleation is studied in detail. A local expansion of atomic volume induces protodefect formation.
