Frictional crack initiation and propagation analysis using the numerical manifold method
Zhijun Wu,Louis Ngai Yuen Wong +1 more
TL;DR: In this article, the effects of the friction and cohesion on the crack growth from a closed flaw (crack) under compression were investigated, based on the contact technique of the NMM and the incorporation of the Mohr-Coulomb crack initiation criterion.
Journal ArticleDOI
Experimental investigation of thermal effects on dynamic behavior of granite
TL;DR: In this article, the authors evaluate the thermal effects on the geophysical properties of granite and show that the dynamic strength decreases linearly as temperature increases but increases as the impact pressure increases.
Journal ArticleDOI
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
Micro-mechanical modeling of the macro-mechanical response and fracture behavior of rock using the numerical manifold method
TL;DR: In this paper, a micro-mechanical based numerical manifold method (NMM) is proposed to investigate the micromechanisms underlying rock macroscopic response and fracture processes.
Journal ArticleDOI
Effects of particle size on crushing and deformation behaviors of rockfill materials
TL;DR: In this paper, single-particle crushing tests were carried out on rockfill materials with nominal particle diameters of 2.5mm, 5mm and 10mm to investigate the particle size effect on the singleparticle strength and the relationship between the characteristic stress and probability of nonfailure.
