An experimental investigation on fatigue characteristics of granite under repeated dynamic tensions
TL;DR: In this paper , the authors investigate the dynamic tensile fatigue characteristics of rock, and they show that the peak stress of granite decreases, while the peak strain increases with increasing impact number under a given impact stress.
Journal ArticleDOI
A New Characterization Method for Rock Joint Roughness Considering the Mechanical Contribution of Each Asperity Order
TL;DR: In this paper, the relationship between the mechanical contribution and the morphology contribution of waviness and unevenness was analyzed, and the characterization formula considering the structural contribution of the joint surface was established.
Journal ArticleDOI
Morphological parameters of both surfaces of coupled joint
TL;DR: In this article, the upper and lower surfaces of coupled joints were made with Brazilian tests and each surface was scanned by the Talysurf CLI 2000. Morphological characteristics of joint surface were quantified by statistical and textural parameters.
Journal ArticleDOI
Suggested New Statistical Parameter for Estimating Joint Roughness Coefficient considering the Shear Direction
TL;DR: Based on the concept of area difference, the average of positive area difference (Sa) and sum of positive areas difference (Ss) were first proposed to reflect the roughness of joint surfaces on the basis of directional property, and their fitting relationship with JRC was also investigated as mentioned in this paper.
