For a determination of the effect the geometry of a Single Edge Crack Tension (SECT) specimen with graded region between two homogenous basic materials (see Fig. 1) is used in numerical simulations. A continuous and smooth graded structure is modelled with various magnitude of non-homogeneity. Fracture parameters are calculated along the crack front for different crack length.
