Abstract
The influence of anisotropy of crystallographic origin on both fracture toughness and the rate of
stage-II ductile fatigue crack growth in textured metals is discussed in terms of a plane-strain small
geometry change solution for plastic non-hardening materials (a Prandtl-type slip-line field solution
accounting for anisotropy). Results corresponding to FCC or BCC metals sliding, respectively, on
