Description	Two unlike dislocations gliding in parallel slip planes in a channel of a persistent slip band are considered. Initially they are kept apart in straight screw positions. As the dislocations are pushed by the applied stress between two walls in the opposite directions, they bow out and attract one another forming a dipole. With the increasing stress the dislocations become more and more curved, until they separate. The dislocations are modeled as planar curves and their glide is simulated using the flowing volume method and the method of lines. The objective of the simulations is to determine the escape stress in the channel needed for the dislocations to escape one another Two unlike dislocations gliding in parallel slip planes in a channel of a persistent slip band are considered.

Pod vlivem vnějšího pole jsou dislokace tlačeny proti sobě, ohýbají se a přitahují se tak, že vytváří dipól. Se zvyšujícím se napětím jejich křivost roste až dojde k jejich odtržení. Dislokace jsou modelovány jako rovinné křivky a jejich skluz je simulován metodou tekutých objemů a čar. Cílem simulací je určit napětí v kanále, které je nutné k tomu, aby se dislokace oddělily (cs)
