Atomic mechanisms of fracture nucleation and fracture development in two-dimensional crystals in thermodynamic equilibrium. II. Two-phase systems

Abstract

The method of molecular dynamics is used to study the fracture mechanisms of two‐phase crystal systems containing low‐and high‐strength inclusions. It is shown that the fracture depends on temperature and applied stress and can be associated with the rupture of interatomic bonds in or near inclusions and the subsequent emission of dislocations from the tips of cracks formed.
