Effect of Bedding Angle and Confining Pressure on the Brittleness of Geomaterials: A Case Study on Slate

Figure 14

Relationship between energy, or work, related to brittleness and confining pressure. (a) The energy accumulated at the axial prepeak stage. (b) The work done by press at the axial postpeak stage. (c) The residual strain energy at the postpeak stage.
