An investigation of thermal effects on micro-properties of granite by X-ray CT technique
TL;DR: In this article, the thermal effects on micro-properties of granite were experimentally studied and two indexes (heterogeneity coefficient and anisotropy coefficient) were proposed to describe the micro properties of granite.
Journal ArticleDOI
On the tensile mechanical characteristics of fine-grained granite after heating/cooling treatments with different cooling rates
TL;DR: In this article, the results from tests performed to investigate the tensile mechanical characteristics of granite after exposure to heating and cooling treatments were analyzed using the Brazilian disc method, and the results showed that the water-cooled samples exhibited the largest decrease in P-wave velocity and the largest numbers of newly generated cracks on the surface, which indicates that the samples heated and cooled at higher cooling rates were more susceptible to the heating/cooling treatments.
Journal ArticleDOI
Understanding the fracture behavior of brittle and ductile multi-flawed rocks by uniaxial loading by digital image correlation
TL;DR: In this article, a comparison study on brittle and ductile laboratory rock-like specimens that contain nine pre-existing flaws subjected to uniaxial compression is conducted, and the fractal dimension estimation method is introduced to quantitatively track the fracture process.
Journal ArticleDOI
A zero-thickness cohesive element-based numerical manifold method for rock mechanical behavior with micro-Voronoi grains
TL;DR: Since the NMM adopts an implicit scheme to solve the problem, a large time step is allowed, which makes it possible to realistically model the static loading condition without need of raising up the loading rate required by other explicit-based methods.
Journal ArticleDOI
Spatial gradient distributions of thermal shock-induced damage to granite
TL;DR: In this paper, the spatial gradient distributions of thermal shock-induced damage to granite with respect to associated deterioration mechanisms were investigated by computed tomography (CT) and image analysis techniques, and the influence of the preheating temperature on the spatial gradients of the damage was discussed.
