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
{111} 〈110〉 or {110} 〈111〉 systems are presented. Remarkable effects of both texture toughening and
fatigue crack growth rate anisotropy are predicted. Stronger effects are anticipated in more
anisotropic metals (HCP).
