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.

Deterministic models of crack growth can be fitted to experimental data. This paper shows that stochastic growth models are easy to use and provides a simple framework for data analysis. A simple transformation allows the standard linear regression model to be used and opens the way for a fully Bayesian analysis.

In the paper the equations of stable and unstable crack growth are reconsidered in the framework of thermodynamics. The new approach is proposed that is tested for the fast crack growth. The results obtained reflect qualitatively the main features of this process.

So far two types of crack extension have been considered: stable crack extension starting at K 1 =K 10 and unstable crack extension, if K 1=K 1inst is reached (or at K 1 =K 1c for a material with a flat crack growth resistance curve). A third type of crack extension is called subcritical crack extension.
