網頁2024年3月26日 · The thermomechanical behavior of coal and sandstone during excavation using the freezing method is a new challenge for coal mining and geotechnical engineering. In this paper, the influence of temperature on the mechanical characteristics and fracture patterns of two types of saturated rocks (coal and sandstone) were investigated. A series … 網頁Just two independent slip systems may be provided by this slip system, which causes it to frequently develop cleavage fractures and display brittle fracture behavior. Some reports stated that the basal slip of zinc is {0002}<11 2 ¯ 0>, the conical slip system includes {11 2 ¯ 2}<11 2 ¯ 3>, and the cylindrical slip is {10 1 ¯ 0}<11 2 ¯ 0>.
網頁The brittle compressive fracture under uniaxial loading of fresh-water, granular ice Ih has been studied. Measurements are reported of the fracture stress at temperatures from −10 to −50°C at strain rates of 10 −3 and 10 −1 s −1 for grain sizes from approximately 1 to 10 mm. Also a summary is reported of measurements by Jones et al .
