Abstract
Explanation of the stick-slip dislocation motion, which is experimentally observed in situ, goes beyond the scope of the simplest models. The inclusion of extra degrees of freedom which govern the change-over between the glide and sessile dislocation states makes possible a general description of the dislocation dynamics. The solution to the appropriate statistical model is obtained in the present work. This solution describes the mechanisms of the stick-slip dislocation motion and the associated features of plasticity of the materials.Keywords
