The simple method developed by Kachanov (1985) for multiple interacting cracks in homogenous medium is extended to predict complex stress intensity factor for multiple split type interface cracks. Calculations are implemented for two equal cracks and infinite row of periodic cracks at the interface between two dissimilar isotropic materials.

This paper presents a new numerical method for obtaining the complex stress intensity factor with an interface crack in bi-materials using photoelastic isochromatic fringe numbers N. The theoretical solution of stress field at the crack tip was deduced from Muskhelishvilis stress function and an undetermined term σ0 which is a function of material ...

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

A Cauchy type singular integral equation along a finite real interval and with a weight function with complex singularities at the end-points of the integration interval can be numerically solved by reduction to a system of linear equations, by using an appropriate numerical integration rule associated with the Jacobi polynomials, in exactly the same ...

This work presents the results from an analysis which considers the interaction between a crack and surrounding microcracks. The method of complex variables is used to derive explicit expressions for the stress intensity factors. The results are computed and discussed for a variety of geometrical configurations of microcracks, with the intent of ...

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

Abstract A finite element computer program EPAS-J1 was developed to calculate the stress intensity factors of three-dimensional cracks. In this program, the stress intensity factor is determined by the virtual crack extension method together with the distorted elements allocated along the crack front. The program also includes the connection elements

Overload effects have been studied for center-cracked tension (CCT) specimens of aluminum alloy 2124-T351. The results show that the retardation of crack propagation due to overloading, which is not taken into account by the Paris relation, can be explained by variation in the U ratio as defined by Elber.
