In addition, cracks may close under compressive loading, which also increases the complexity of the problem. The fatigue growth behavior for surface cracks under biaxial loadings was studied by fatigue tests of HTS-A steel. According to experimental evidences, it is concluded that the transverse ...

Then, approximate SIF values for notched shells with cracks can be computed from Eq. (6). Now the stress field in a notched spherical shell (r*=1) under an internal pressure is Conclusions In the present paper, the behaviour of a part-through-cracked notched shell is examined. For ...
In modern industry, ICT is especially useful for analyzing inner defects of complex and close work pieces. The common defects of work pieces include gas cavities, slag inclusions, cracks and shrinking cavities. Only cracks are often caused by fatigue usage. Precisely extracting a crack is ...
