Abstract

One of the important aspects of the mechanism of brittle cracking is the geometry of fracture, i.e. its morphology and trans- or intercrystalline image. In the paper consideration has been given to fractures of dolomite and quartzite specimens obtained as a result of direct tensile test and brazilian test. Reconstruction of specimens was obtained by gluing. The linear stereological analysis was performed. Two groups of crystals have been identified: (1) crystals not adjacent to the fracture, (2) crystals adjacent to the fracture. It has been found in particular, that the mean intercept length of crystals in group 2 is significantly greater than the mean intercept length of crystals in group 1. Trans- or intercrystalline cracking depends not only on the type of the rock, but also on the mode of obtaining the fracture.

Keywords : cracking of rocks, intercrystalline fracturing, linear stereological analysis, transcrystalline fracturing
