WebApr 11, 2024 · In order to discuss the influence of the geometry size of the defect on the energy release rate, the elastic constants of the materials as shown below were selected: C 44 = 70 GPa, K 2 = 120 MPa, and R 3 = 1.8 GPa. Then, we set a = 0.001 m, σ z y ∞ = 6 MPa, and H z y ∞ = 4 MPa. The unit of energy release rate is N/m in Table 1 and Table 2. WebA given strain is associated with a certain linear combination of elastic constants. For cubic systems, including diamond, there are three independent elastic constants, C 11, C 12, and C 44. One linear combination of the elastic constants is obtained from the bulk modulus
