The paper presents computational experiments performed for the dynamic model of the Frank−Read dislocation source. The model is based on numerical solution of parabolic type partial differential equations. The number of forming dislocation loops has been plotted as a function of source base value and applied force magnitude. Dislocation loop velocity graphs during the development of sources with different bases and different stresses have been obtained. Characteristic forms taken by the dislocation loop source are shown for each velocity graph.
