Fracture Tests

Dimple fracture tests are conducted under mode I and mixed mode lading conditions. Dimple fracture zone and shear-lip fracture zone are observed by scanning electron microscope precisely. It is found that crack growth direction is affected largely by the change of loading condition. It is also found that the differences of fracture pattern between mid-plane and at free surface are very large. Void diameter and crack growth direction are measured. Numerical simulation is conducted to simulate fracture tests in three-dimensional field. Gurson’s constitutive equation is used and large deformation analyses are conducted. It is assumed that void nucleation is controlled by both plastic strain and stress. Numerical results are compared with those of experiments. It is found that results of numerical simulation agree well with those of experiment qualitatively.

Dominant Influence

Creep–fatigue tests were carried out on Jethete M152 at 550°C under mode I, mode II, and mixed mode ( K1/ KII ≈ 1.6) conditions. The results were correlated and compared with corresponding fatigue and creep data. The results indicated that damage due to creep caused a larger increase in fatigue crack growth rate than a simple superposition model would predict. Also creep appeared to have a more dominant influence than fatigue on crack growth direction.
