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 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

COMPLEX STRESS INTENSITY FACTORS FOR A CRACK IN A BIMATERIAL BRAZILIAN TEST SPECIMEN
Fatigue & Fracture of Engineering Materials & Structures, 1994Abstract— The stress field in front of a crack tip lying in a plane bimaterial interface is always of a complex nature. The stress intensity factor characterising its asymptotic variation is therefore a complex number and its assessment from a numerical calculation requires the separation of the particular loading modes by an appropriate method.

Stress-Intensity Factors and Complex Path-Independent Integrals
Journal of Applied Mechanics, 1980Path-independent integrals about crack tips may be used to estimate stress-intensity factors at crack tips in plane and antiplane elasticity problems. In this paper a new class of such integrals is established by using complex stress functions and the trivial application of the Cauchy theorem of complex analysis.

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.

A simple method for calculating the stress intensity factors for complex 3D cracks at a notch
Engineering Fracture Mechanics, 2016Abstract When performing a safety/durability assessment of structural components it is often necessary to consider both fatigue crack propagation and failure by fast fracture among the possible modes of failure. In this context the stress intensity factors at crack tips are important parameters for estimating residual life and criticality.

Determination of stress intensity factors for cracks of complex shape in anisotropic plates
Journal of Applied Mechanics and Technical Physics, 1987The 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.

Stress intensity factors for half-elliptical surface cracks subjected to complex crack face loadings
Engineering Fracture Mechanics, 1984Abstract The disagreement in the literature on the stress intensity factors for surface cracks is considerable. It is also noted that not enough attention has been given to the behaviour of surface cracks in stress fields more complex than uniform tension and bending, although such solutions are needed for crack problems in, e.g. thermal and residual

Engineering Failure Analysis, 2007
Abstract In this paper, an effective numerical method for analyzing interacting multiple cracks and complex crack configurations in infinite linear elastic media is presented. By extending Bueckner’s principle suited for a crack to a general system containing multiple interacting cracks, the original problem is divided into a homogeneous problem (the
