On the photoelastic determination of complex stress intensity factors
Engineering Fracture Mechanics, 1979Abstract An improvement of the one-parameter extrapolation method of photoelastic determination of complex (mixed-mode) stress intensity factors at straight or curvilinear crack tips in a plane isotropic elastic medium due to Smith et al . [12, 13] can be achieved by measuring the absolute value of such a factor on the isochromatic fringes along ...

Evaluation of a Complex Stress Intensity Factor of Interface Cracks: A Perturbation Approach
Journal of Applied Mechanics, 1993The complex stress intensity factors are evaluated for a crack located on a bimaterial interface. The oscillatory index \(\varepsilon\) is treated as a small parameter of the problem. Two cases are considered: 1) a semi- infinite crack loaded by a distributed traction along the crack boundary, 2) a finite crack with tractions prescribed on its surface.

Determination of stress intensity factors for cracks of complex shape in anisotropic plates
Journal of Applied Mechanics and Technical Physics, 1986The application of analytical methods to the problem of fatigue crack propagation and branching is complicated by the shortage of information on the stress distribution near the tip of cracks of complex configuration. A discussion of this problem and a survey of the studies in this area can be found in [1], for example.

An improved experimental evaluation of the complex stress intensity factors from isopachics
Journal of Physics D: Applied Physics, 1985The optical evaluation of the complex stress intensity factors at the tips of an inclined central crack in an infinite sheet subjected to a biaxial load at infinity was studied by using the appropriate number of higher-order terms in the series representation for stresses for the isopachic fringe pattern.

Evaluation of Complex Stress Intensity Factors in Debonded Sandwich Beams
Mechanical Behavior of Advanced Materials, 1998Abstract The overall objective of the project are to develop methods to characterize the damage tolerance of sandwich panels with disbonded face sheets under inplane compression, and to develop a criterion for predicting the allowable disbond for a given set of inplane loading. As part of the study we characterize the mixed mode fracture

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 from the surface treatment.

Journal of Pressure Vessel Technology, 2003
Fatigue cracks in shot peened and case hardened notched machine components and high-pressure vessels are subjected to the stress fields induced by the external load and the residual stress resulting from the surface treatment or autofrettage. Both stress fields are usually nonuniform and available handbook stress intensity factor solutions are in most ...

Complex Stress Intensity Factors in Bent Plates With Cracks
Journal of Applied Mechanics, 1982The experimental method of caustics was applied to the study of asymmetric bending of isotropic cracked plates and to the determination of the complex stress intensity factors (S.I.F’s) at the crack tips. It was shown that the method of reflected caustics is convenient for detecting and evaluating both KI and KII stress intensity factors.

Complex stress intensity factors at tips of cracks along interfaces of dissimilar media
Engineering Fracture Mechanics, 1981Abstract The method of reflected caustics was used to determine the complex stress intensity factors at the tips of cracks having any shape, which lie at the interface of two dissimilar elastic media. For the evaluation of complex S.I.Fs two measurements of appropriate lengths have to be made on the caustic formed at the crack tip. These measurements
