N2 - In the present paper, the extent of surface regions in cracked bodies subjected to mode-I loading was examined, which is important for a proper definition of finite element meshes. Different specimen geometries with and without lateral notches, representative of several engineering situations, were selected. Realistic crack shapes were considered in this analysis by employing a 3D-FE automatic crack growth technique. A triaxiality parameter (h) was calculated for different loading and geometrical parameters, namely thickness, crack length, crack shape and particularly radius of lateral notches. Criteria were defined to objectively define the extent of surface and near surface regions, S and S , respectively (slope of h>0.9 for S and 0.1
