Effect of the free surface on crack behaviour in cracked graded structures
Original language 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 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. The influence of cracklength on the size of free surface affected region has been studied by estimating the stress singularity exponent p along the crack front, see Fig. 4. The effect of free surface was getting more significant with increasing crack length. The value of thestress singularity exponent decreases on the free surface to 90% of the magnitude in the middle of the specimen for all studied crack lengths.
