• In general, a dislocation line cannot end inside of a crystal. The exception is at a node, where three or four dislocation lines meet.

• At a node two dislocations with Burgers vectors b1 and b2 combine to produce a resultant dislocation b3.

• The vector b3 is given by the vector sum of b1 and b2 .
