| Abstract | The use of a high speed video system allows one to precisely observe the cracking mechanisms, in particular if shear or tensile fracturing is taking place. The present experimental study on gypsum and marble specimens confirmed that tensile wing cracks (TWCs) are in most cases the first cracks to appear in fracture propagation from existing flaws independent of aperture and material. The study, in addition, has shown that complex additional cracking occurs which depends on orientation of the existing flaws and material type. Either the TWCs or the other tip cracks produce failure. Also important is the formation of a process zone which could be visually observed in some marble experiments, but not in gypsum experiments.
