Journal ArticleDOI
Fracture toughness testing of brittle materials using semi-circular bend (SCB) specimen
TL;DR: The semi-circular bend (SCB) specimen has been used for many other applications as mentioned in this paper, such as testing of in situ conditions such as elevated temperature, confining pressure and pore water pressure.
Journal ArticleDOI
Fracture toughness determination of layered materials
TL;DR: In this paper, the static fracture toughness of oil shale, which is a typical layered rock containing fossil fuel, was measured using static tests, and the fracture toughness was determined using a stress intensity factor method, a compliance method and a J- integral based method.
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
New specimens for mixed mode fracture investigations of geomaterials
Ken P. Chong,Mahinda Kuruppu +1 more
TL;DR: In this paper, the fracture load is obtained by compressing the specimen to failure, and the effect of crack length on the normalized stress intensity factor for the proposed geometry is investigated by finite elements.
