TL;DR: In this paper, the failure load of pre-cracked disks was measured, showing the decreasing effects of the cracks and their orientation on the final failure load, and the breakage process of the disks was studied by inserting single and double cracks with different inclination angles.

TL;DR: In this article, the cracks coalescence path in Brazilian disc and rectangular specimens made from rock-like material containing multi-holes are investigated, and the results presented in this paper validate the accuracy and applicability of these crack analyses procedures.

TL;DR: In this paper, the breaking load of pre-cracked Brazilian disc specimens is measured under compressive line loading and it is shown that as the number of cracks increases, the final breakage load of the specimen decreases.

TL;DR: In this article, a coupled numerical-experimental analysis of crack propagation, cracks coalescence produced during the cutting action of TBM disc cutters has been studied, and a numerical code is developed based on the higher order semi-infinite displacement discontinuity method (HSDDM) for the numerical simulation of rock-cutting process.

TL;DR: In this article, the effects of joint number and angularities on the both of the compressive behavior of joint's bridge area and its tensile strength were investigated using experimental and extend finite element method.
