Crack patching: Predicting fatigue crack growth
Theoretical and Applied Fracture Mechanics, 2006This paper examines the crack growth history of a range of test specimens, and cracks repaired with a composite patch, and shows that in the low to mid range ΔK region there is a near linear relationship between the log of the crack length and the number of cycles.

A concise review is presented of widely used theories for the quantitative description of the growth of cracks in creeping media. Deficiencies are highlighted of the way in which calculations of component lifetimes have been carried out. New data is presented which overcomes some of the deficiencies, and results are presented of calculated component ...

Singular integral equations have been applied to the quasistatic growth of an edge crack in an isotropic elastic half-plane when a self-balancing load is given at the crack edges. The path has been calculated by a step method with allowance for the stress redistribution during the crack growth, and the growth direction has been determined from the σθ ...

Materials design and development for resistance to stress corrosion cracking depends upon an understanding of the crack-growth mechanism. The factors controlling stress corrosion cracking may be classified as environmental, material and mechanical. This overview examines the state of the art in stress corrosion cracking and reviews such considerations ...

Fatigue in materials subjected to repeated cyclic loading can be defined as a progressive failure due to crack initiation (stage I), crack growth (stage II), and crack propagation (stage III) or instability stage. For instance, crack initiation of crack-free solids may be characterized by fatigue crack nuclei due to dislocation motion, which generates ...

Publisher Summary This chapter discusses subcritical crack growth, which is usually the result of a stress-enhanced reaction between the ceramic and ambient moisture. The effect of subcritical crack growth on the strength of ceramics can be understood by using the science of fracture mechanics, which provides methods for quantifying crack growth ...

In this chapter we will first present a synopsis of the theoretical foundation of linear and nonlinear fracture mechanics. In recent years a number of monographs, textbooks and conference proceedings have been published on the subject of fracture mechanics (see for example [1–10] where further references are listed).

On the background of the historical evolution of the subject area, the current knowledge on creep crack growth is reviewed. The discussion is grouped around the C* integral, which is the appropriate load parameter for describing creep crack growth in ductile materials.

Creep has been a subject of considerable practical and theoretical interest. In recent years, however, there has been a shift in the way creep has been viewed. In earlier times creep was looked at as a plastic deformation process with the emphasis on studying plastic flow as a function of time, temperature, stress, etc.
