... of the Pennsylvania blue sandstone. It is shown that for a more ductile material, there is less scatter of micro-cracking at the peak load. Furthermore, the ductility parameter appears to be a good tool in controlling the ratio of compressive to uniaxial tensile strength of rock. While the ductility of the filling...

... Abstract: Fracture process zone is a non-linear region made of micro-cracks and damaged points around crack tips in quasibrittle materials such as rock and concrete. Most of the studies in the literature are concerned with characterizing the process zone at the peak load. In this study...

... and material ductility on the length and width of the FPZ at the peak load. The material ductility was controlled by using different slopes for the post-peak behavior of contacts between the circular particles in tension. A statistical approach is proposed to more objectively calculate the width and length...
