Statistical considerations in linear elastic fracture mechanics
Journal of Aircraft, 1975Critical defect size distributions are estimated for various metals and for hot pressed silicon nitride using the Monte Carlo method. With regard to the critical flaw size computation, results obtained for the numerous materials are compared to the sensitivity or probability of detection of particular flaw sizes based on existing nondestructive ...

Linear elastic fracture mechanics of duralumin
Canadian Metallurgical Quarterly, 1969AbstractOne desirable improvement of high-strength aluminum alloys often showing considerable anisotropy is the increase of their notch toughness in certain grain orientations. Although we know that material properties such as yield stress, fracture toughness, fatigue or stress corrosion behaviour generally have a strong directional dependence, the ...

Some Applications of Linear Elastic Fracture Mechanics
2016The approach to fracture prediction that we discussed in the preceding chapter has been applied to a wide variety of materials in many types of applications. While steels, aluminum alloys, and titanium alloys have received the greatest attention with an extensive data compilation [1] now being available, many other metals have also been studied.

The Basis of Linear Elastic Fracture Mechanics
2016In this chapter we will discuss the use of elastic solutions to predict the strength of parts containing sharp cracks. Immediately, we are faced with the difficulty that, whether we consider the line crack or the elliptical crack with semiminor axis shrunk to zero, the stresses at the crack tip are infinite for any value of load.

Introduction to linear elastic fracture mechanics
2001Publisher Summary This chapter focuses on the concept of linear elastic fracture mechanics (LEFM). LEFM is the basic scheme used for most of the protocols. It has a secure theoretical basis in that all energy dissipation is associated with the fracture process and the deformation that occurs is linear elastic.

Crack stability in linear elastic fracture mechanics
International Journal of Fracture Mechanics, 1969A linear elastic fracture mechanics analysis of the conditions that produce crack instability is presented. If the initial crack extension causes the change in crack-tip resistance to be negative with respect to the change in crack-tip loading, the crack will continue to propagate even though the loading agent remains stationary, and the crack is ...

Linear Elastic Fracture Mechanics (LEFM) and Applications
2001In brittle fracture it is assumed that failure in an elastic material takes place when the available elastic energy is adequate to overcome the energy necessary to propagate a crack and to create new crack surfaces. At the instant of instability, the stresses at the apex of an elastic crack must have sufficient magnitude, capable of driving the crack ...
