Stress Concentration in the Bulk Cr₂O₃: Effects of Temperature and Point Defects

Figure 4

Results obtained for a 1 × 1 × 2 supercell of Cr₂O₃. (a) Stress σ (GPa) versus strain (Å) curve that provides the ideal tensile test. is the maximum tensile strength. (b) Crystal structure showing the fracture at two points.
