摘要：
The influence of elastic anisotropy on dislocation instability in cubic elastic media is investigated systematically using the Stroh sextic formalism. The iteration method is used to calculate the dislocation energy factor of straight dislocations and the line tension of planar curved dislocations. By examining the inverse energy surface for various Burgers vectors, the general features of the dislocation instabilities in cubic elastic media are obtained.
