Description	The influence of the singularity induced by the free surface on the behaviour of a body with a V-notch is investigated in this paper. Attention is focused mainly on the change of the singularity and the stress state through the thickness of a three-dimensional specimen. Numerical finite-element analysis of the tension loaded specimens with a V-notch were performed. The displacements and the stresses from the analysis were used to estimate the power of singularities using a log-log regression analysis along the crack front. It was found that in the middle of the specimen singularity of the V-notch is dominant this can be found using analytic equations describing two-dimensional stress distribution around the sharp V-notch. This singularity is dependent only on the V-notch angle. The second singularity is dominant at the free surface and their influence becomes nearly zero away from boundary layer. The thickness of boundary layer (region influenced by corner singularity) depends only on the Poisson's ra The influence of the singularity induced by the free surface on the behaviour of a body with a V-notch is investigated in this paper.
