WebApr 13, 2024 · 1.Introduction. Local tensile stress significantly affects the failure characteristics of rock under tension, bending and even compression conditions [1], [2].Fracture toughness, as a fundamental property of rock materials, is as important as tensile strength in fracture analysis [3], [4].Rocks are different from metal materials, and … WebThe material has now moved into the region referred to as plastic deformation. In practice, it is difficult to identify the exact point at which a material moves from the elastic region to the plastic region. As shown in the figure below, a parallel line offset by 0.002 strain is drawn. Where that line intercepts the stress-strain curve is ...
