Interacting multiple cracks with complicated crack surface conditions
International Journal of Fracture, 1996In solving multiple cracks problems for the strong crack interactions, crack surfaces that are not always open even under remote tension loading, some crack surfaces may contact or even partially contact.

A study into the interaction of intergranular cracking and cracking at a fastener hole
Meccanica, 2013This paper describes the results of a study into a new class of multi-site damage problems, viz: the interaction between multi-layer intergranular cracks and cracks that grow from small naturally occurring material discontinuities at a hole. The nature of the intergranular cracks, which are perhaps better thought of as delaminations rather than cracks,

Interaction of penny-shaped cracks with a half-plane crack
International Journal of Solids and Structures, 1993Three-dimensional interactions between a half-plane crack and penny- shaped cracks which are not necessarily located in the same plane are analysed using the ``weight function'' method of three-dimensional crack analysis. Analytical expressions are given for the interaction kernels in the integral equations with the opening displacements of penny ...

Crack Mechanisms and Crack Interaction in Thin Films
Technical Report Mechanical Engineering, 2012The report contains a description of the theory for throughsurface channeling crack in thin film systems. Key topics and mechanisms are described including channeling criteria, crack interaction and elastic mismatch in the system. A case of radial cracks spreading from a Rockwell indenter is used to describe how the theory can be used to determine ...

On the general treatment of interacting cracks near an interfacial crack
International Journal of Engineering Science, 1996Abstract In this article, the authors provide a generalized approach for the treatment of an interfacial crack interacting with microdefects under antiplane loading. The original problem, which is characterized by complex boundary conditions, is divided into a number of simpler subproblems—each containing either the microdefects or the bimaterial ...

Numerical modeling of crack-defect interaction
Journal of Propulsion and Power, 1989An elastic analysis of the interaction between a main crack and defects was conducted using finite element methods. In the analysis, two different types of defects, voids, and damage were considered. The effects of the size, the location, and the number of voids, and, also, the intensity of damage on the Mode I stress intensity factor and the stress ...

The interaction of a crack with an interface crack as a theoretical model for debonding
International Journal of Fracture, 1990A complex integral equation has been derived which describes the interaction of a crack with an interface crack as well as the limiting case of a kinked interface crack. With the help of this solution a model of the debonding process has been set up.
