Abstract

For strongly anisotropic polymer crystals Peierls barrier for dislocations with the Burgers vector parallel to the molecule axes is so small, that it can be neglected. In such case dissociation of dislocation dipoles should be the basic mechanism of plastic deformation. To study this phenomenon we developed the program, simulating dynamic behavior of a two- dimensional monoclinic polyethylene monocrystal. Numerical experiment has confirmed the theoretical prediction of dissociation stress of dislocation dipole. Effective inertial mass of a dislocation and effective viscosity involved in a dislocation movement were measured.
