Numerical Study on the Fracture Trajectories and Mechanisms of Hole-Contained Brazilian Discs: The Role of Size Effects and Arrangements
This study mostly investigates the effects of the sizes of a single hole and the arrangements of multiple holes on the cracking characteristics of rock-like materials (concrete) under compressive loading based on the extended Non-ordinary state-based peridynamics (NOSBPD) model. The radius sizes of pre-existing single holes overtly affect the fracture trajectories of Brazilian discs. The critical value of the radius of the pre-existing hole can be ascertained to identify the transition of fracture trajectories for single hole-contained Brazilian discs. The numbers and arrangements of pre-existing multiple holes overtly affect the fracture trajectories of Brazilian discs. The extended NOSBPD model can unfailingly predict the breakage trajectories of single and multiple contained holes Brazilian discs. The distribution characteristics of stress fields can analyze the fracture mechanism of flawed Brazilian discs. The stress concentration, the stress concentration transfer, and the stress concentration dissipation can clarify the initiation, growth, and stop of new cracks, respectively.
