Thermally Activated Motion of Dislocations in Fields of Obstacles: Effect of Obstacle Distribution
Zhijie Xu, Catalin Picu
The thermally activated motion of dislocations across fields of obstacles distributed at random and in a correlated manner, in separate models, is studied by means of computer simu…
