The 3D Numerical Simulation for the Propagation Process of Multiple Pre-existing Flaws in Rock-Like Materials Subjected to Biaxial Compressive Loads
TL;DR: In this paper, a meshless numerical method is proposed to simulate the initiation, propagation and coalescence of 3D pre-existing penetrating and embedded flaws under biaxial compression.

Visualization of the complex structure and stress field inside rock by means of 3D printing technology
TL;DR: In this paper, the authors employed 3D frozen stress and photoelastic technologies to characterize and visualize the stress distribution within the fractured coal under uniaxial compression and 3D printed model presented the fracture structures identical to those of the natural coal.

Experimental and numerical study on the fracture process zone and fracture toughness determination for ISRM-suggested semi-circular bend rock specimen
TL;DR: The semi-circular bend (SCB) method suggested by International Society for Rock Mechanics (ISRM) is demonstrated to yield much conservative mode I fracture toughness as mentioned in this paper, and numerically simulated K-resistance curves are demonstrated to have great potential for determining the fracture toughness at the level II.

A damage constitutive model for intermittent jointed rocks under cyclic uniaxial compression
TL;DR: In this article, a coupled damage tensor for intermittent jointed rocks is derived based on the Lemaitre strain equivalence hypothesis, which combines the Weibull statistical damage model for micro-flaws and the fracture mechanics model for macro-joints.

Failure behavior and crack evolution mechanism of a non-persistent jointed rock mass containing a circular hole
Sheng-Qi Yang,Peng-Fei Yin,Yuan-Chao Zhang,Miao Chen,Xiaoping Zhou,Hongwen Jing,Qiangyong Zhang +6 more
TL;DR: In this paper, a model of non-persistent jointed rock masses containing a circular hole is presented and tested under uniaxial compression, and the authors show that the peak strength and elastic modulus of the nonpersistent joints display a U-type variation with respect to the joint inclination.

The failure of brittle solids containing small cracks under compressive stress states
Michael F. Ashby,S.D. Hallam +1 more
TL;DR: In this article, a model for the growth and interaction of cracks in brittle solids under compressive stress states is developed, where a critical stress is required to initiate crack growth: it depends on the initial crack length and orientation, the coefficient of friction and on the stress state.

Fracture coalescence in rock-type materials under uniaxial and biaxial compression
TL;DR: In this paper, the authors investigate fracture coalescence in gypsum specimens under uniaxial and biaaxial compression and show that cracks start at the flaw tip and propagate out of plane as either tensile or shear cracks.

H. Horii,Sia Nemat-Nasser +1 more
TL;DR: In this paper, the elasticity boundary value problem associated with cracks growing from the tips of a model flaw is solved, and the variations of the "ultimate strength" and the orientation of the overall fault plane with confining pressure are estimated.

A note on brittle crack growth in compression
W. F. Brace,E. G. Bombolakis +1 more
TL;DR: In this paper, the growth of cracks in photoelastic material and glass under compression is studied as part of an investigation of brittle fracture of rock, where the most severely stressed crack is inclined at about 30° to the axis of compression.
