|Abstract(s):||The study presented herein deals with an investigation of the dependence of the mode I fracture energy on the fracture path. The relief of the fracture surfaces resulting from direct tensile tests conducted on different types of granites was characterized by means of classical parameters, mean roughness and root-mean-square roughness. These parameters were obtained from the data acquired by a 3D laser topographical inspection system used to capture the texture of fracture surface profiles at various locations of the surface. A scattered linear correlation between fracture energy and the mean (micro)roughness was attained. Additionally, it was found that microstructural aspects, like planear anisotropy and grain size, as well as the weathering state, influence the fracture surface relief.|
