Journal ArticleDOI
Crack Coalescence in Molded Gypsum and Carrara Marble: Part 1. Macroscopic Observations and Interpretation
TL;DR: In this paper, a high speed video system was used, which allowed us to precisely observe the cracking mechanisms and identified nine crack coalescence categories with different crack types and trajectories.
Journal ArticleDOI
Systematic evaluation of cracking behavior in specimens containing single flaws under uniaxial compression
TL;DR: In this paper, the results of an experimental study in which molded gypsum and Carrara marble specimens containing a pre-existing flaw were tested in uniaxial compression were presented.
Journal ArticleDOI
The Brazilian Disc Test for Rock Mechanics Applications: Review and New Insights
TL;DR: In this paper, a linear elastic numerical model is constructed to study crack initiation in a 50mm-diameter Brazilian disc using FLAC3D, and the maximum tensile stress and tensile strain are both found to occur about 5 mm away from the two loading points along the compressed diameter of the disc, instead of at the center of a disc surface.
Journal ArticleDOI
Cracking Processes in Rock-Like Material Containing a Single Flaw Under Uniaxial Compression: A Numerical Study Based on Parallel Bonded-Particle Model Approach
TL;DR: In this paper, a parallel bond model was used to numerically simulate the cracking process in rock-like material containing a single flaw under uniaxial vertical compression, where the inclination of the preexisting flaw was found to have a strong influence on the crack initiation and propagation patterns.
Journal ArticleDOI
Crack Initiation, Propagation and Coalescence in Rock-Like Material Containing Two Flaws: a Numerical Study Based on Bonded-Particle Model Approach
TL;DR: In this paper, the authors studied the crack initiation and coalescence behavior in a rectangular rock-like specimen containing two parallel (stepped and coplanar) pre-existing open flaws under uniaxial compression load, which is a type of bonded-particle model.
