Description	Along with external forces and the macro-geometry of cracked bodies, the local stress intensity factors k (or \delta k) at fronts of brittle and fatigue cracks are also determined by internal residual stress fields and the crack front microgeometry (extrinsic shielding). Consequently, the values of k (\delta k) that represent a real crack driving force can be significantly different from those of the remote K (\delta K). This means that, even in the frame of two-parameter linear-elastic fracture mechanics, a characterization of the crack-tip stress field only by K and T is not sufficient at all.
