The aim of this paper is to test the influence of different crack path models, from oversimplification currently used in literature of a straight crack front orthogonal to the specimen sides to a realistic 3D crack path. On the basis of experimental features observed for Ti17 and Ti6242 alloys under multiaxial loading, a sensitivity analysis is proposed to address the impact of realistic 3D crack path on SIF and FCGR assessment.
