Abstract
The influence of elastic anisotropy on dislocation instability in cubi c elastic media is investigated systematically using the Stroh sextic formalism. The iteration method is used to calculate the dislocation e nergy factor of straight dislocations and the line tension of planar c urved dislocations. By examining the inverse energy surface for variou s Burgers vectors, the general features of the dislocation instabiliti es in cubic elastic media are obtained.
