WebDec 1, 2024 · Rock masses often behave quasi-brittle, which allows the use of linear elastic fracture mechanics (LEFM) theory to predict fracture growth. In the context of LEFM, mode I and mode II fracture toughness represent the material resistance against brittle fracture growth due to tension and shear, respectively. Reliable measurement of these ... WebThese formations involve numerous brittle to semi-brittle (or ductile) structural discontinuities including tensile, hybrid, and shear fractures and compactional shear bands. 15, 16 The uniaxial ...
WebBrittle deformation. Fractures are forms of brittle deformation. There are two types of primary brittle deformation processes. Tensile fracturing results in joints.Shear fractures are the first initial breaks resulting from shear … WebA brittle crack was observed in a thin-walled section of the coupling. A portion of the coupling was cut in order to expose the fracture surface for observation, as shown in …
WebApr 1, 2003 · The fracture occurred at θ0 =−70° rather than at θ0 =0 indicates that the fracture is caused by tensile stress rather than shear stress. Therefore the fracture should be related to Mode I instead of Mode II. WebA low yield stress (25 Pa) leads to creep dynamics in the absence of fractures. An intermediate yield stress (144 Pa) leads to the development and interaction of opening …
