About this book. This monograph deals with the part of the field of experimental rock deformation that is dominated by the phenomena of brittle fracture on one scale or another. Thus a distinction has been drawn between the fields of brittle and ductile behaviour in rock, corresponding more or less to a distinction between the phenomena of ... http://mpec.scripts.mit.edu/peclab/
WebSummary. The processes by which rocks and minerals are deformed in the earth's crust and mantle can be studied in the laboratory by subjecting samples to a variety of stress … WebSep 25, 2024 · Mining-induced hydromechanical behavior of sandstone is critical to mining safety and disaster prevention. To investigate the evolution behavior of the mechanical and permeability properties of sandstone, mining-induced stress was imitated by increasing axial stress and decreasing confining stress, and a set of hydromechanical experiments were …
Web3.2. Strength and Deformation Properties. Figure 7 shows the axial stress-strain curves of intact and flaw-contained sandstone specimens under uniaxial compression. From Figure 7, the strength and deformation parameters of tested sandstone specimens, including uniaxial compression strength σ c, peak strain ε c, and elastic modulus E s, can easily be obtained. WebSummary Geophysical methods rely on the accurate determination of physical and mechanical properties of rocks. However, these properties are intimately related to microscopic features such as pore shape and distribution, grain orientations, degree of saturation and fluid distribution. The present contribution reports the development and …
WebAbstract. Eighteen typical igneous or metamorphic “basement” rocks have been experimentally deformed at about 1% main under “shallow” conditions (1 kbar confining pressure, 150°C) and, together with two important rock-forming minerals — biotite and plagioclase — udner “deep” conditions (5 kbar, 500°C). Under shallow conditions ...
