Effect of the free surface on crack behaviour in cracked graded structures
Result description
The aim of the paper is to study the free surface effect on crack behaviour of a crack located in a graded structure. For a determination of the effect the geometry of a Single Edge Crack Tension (SECT) specimen with graded region between two homogenousbasic 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.
