In this chapter, methods for obtaining the stress intensity factors, interface energy release rate and phase angles are presented for interface cracks between two anisotropic materials. These methods include displacement extrapolation, the conservative interaction energy or M-integral and the Virtual Crack Closure Technique. Although these methods have been formulated with the finite element method in mind, they may be adapted to all numerical techniques which provide field quantities.
