| description | This work presents an estimation procedure to determine the fracture toughness parameters J and CTOD for SE(B) specimens using the eta method. The main purpose is to obtain numerically calibrated h (eta) factors which are applicable to an extensive range of relative crack dimensions (0.05 £ a/W £ 0.7) and material hardening properties. The analysis results enable the construction of functional forms which describe the variation of the h factors with crack size (a/W) and material hardening properties, n. The procedure provides more accurate toughness values of J and CTOD from laboratory experimental measurements of fracture toughness. |
