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

Figure 3

(a) Stress (GPa) versus strain (Å) curve that provides the ideal tensile test. is the maximum tensile strength. (b) Crystal structure of Cr₂O₃ bulk, showing position where the fracture happens; (c) Cr₂O₃ bulk system with fracture in the middle. The blue atom corresponds to the specific Cr atom and green atoms are the O forming the octahedron.
