...Zhaoyu Jin; Xin Wang This paper presents the application of the weight function method for the calculation of stress intensity factors for surface semi-elliptical cracks in finite thickness plates subjected to arbitrary two-dimensional stress fields. A new general mathematical form of point load...

... Standard E647 load-reduction method and (2) compression precracking. After compression precracking (CP), three different loading sequences were used: (1) constant amplitude (CPCA), (2) load reduction (CPLR), and (3) constant stress-intensity factor (CPCK). The crack-compliance method was used to determine...

... experimentally and theoretically. The stress intensity factors due to the residual stresses in a brazed T-joint of compressor impellers were measured by using the cut compliance method. It was found that residual stresses are present but relatively small. They do not affect the endurance stress significantly...

... stress intensity factor solutions. Crack growth at the center of the bolt correlates well with Toribio’s (Int. J. Fract., Vol. 53, 1992, pp. 367–385) finite element based predictions for open threaded bolts. Crack growth rate is much higher at the surface than at the center. In case of nut-loaded bolts...

...) linear superposition of stress intensity factor, K, solutions of the non-cold worked hole and the residual stresses. Such predictions have shown various levels of agreement with the overall fatigue life and have generally underpredicted the crack growth over the majority of life. An inverse process...

... of surface cracked plates under biaxial tension loading is presented. As a comparison, the assessment of surface cracked plates under uniaxial tension loading is also presented. The elastic T -stress is used as the constraint parameter. The calculation of the stress intensity factors, T -stresses and limit...

...Z Wu; G Glinka; H Jakubczak; L Nilsson One of the difficulties in using fracture mechanics is in determining stress intensity factors of cracked structural and mechanical components. The cracks are often subjected to complex stress fields induced by external loads and residual stresses resulting...
