ISRM-Suggested Method for Determining the Mode I Static Fracture Toughness Using Semi-Circular Bend Specimen
TL;DR: In this article, a semi-circular bend specimen is used to determine the mode I fracture toughness of sedimentary rocks using three different core-based specimens and tests were performed on a typical laboratory compression or tension load frame.
Journal ArticleDOI
Combined effects of increasing temperature and confining pressure on the fracture toughness of clay bearing rocks
TL;DR: In this paper, the effects of increasing temperature and confining pressure on the fracture toughness of clay bearing rock, fracture toughness experiments were carried out at temperatures elevated from room temperature up to 200°C using single edge-notched round bar in bending (SENRBB) and semi-circular bend (SCB) specimens of Kimachi sandstone and Tage tuff.
Journal ArticleDOI
Effects of temperature and confining pressure on mixed-mode (I–II) and mode II fracture toughness of Kimachi sandstone
TL;DR: In this article, the International Society for RockMechanics (ISRM) has incorporated the chevron-notched bendspecimen and short rod specimen into the standard method for measurement of the fracture toughness of rock.
Journal ArticleDOI
Numerical analysis to better understand the mechanism of the effects of ground supports and reinforcements on the stability of tunnels using the distinct element method
TL;DR: In this paper, the effect of ground supports and reinforcements on tunnel stability was investigated using the distinct element method, and it was revealed that supports help to form ground arches in the sandy ground.
Journal ArticleDOI
Evaluation of Mode I Fracture Toughness Assisted by the Numerical Determination of K -Resistance
TL;DR: In this article, the authors used semi-circular bend (SCB) and chevron bend (CB) specimens to investigate the mode I fracture toughness of a rock.
