Linear elastic fracture mechanics

2022
Abstract This chapter describes the asymptotic elastic crack tip solutions for stress and displacement fields, and the concept of stress intensity factors for Mode I, Mode II, and Mode III loadings. Since in most engineering applications globally brittle fracture of a structure occurs by crack propagation in a direction perpendicular to ...

Limits of Linear Elastic Fracture Mechanics

Journal of Pressure Vessel Technology, 1984
This paper presents a simple procedure for determining the validity limits of linear elastic fracture mechanics (LEFM) calculations for low alloy steel (ferritic) structures. The procedure is limited to structures with flaws whose depths are 50 percent or less of the wall thickness of the component at the flaw location and to components which can be ...

Linear Elastic Fracture Mechanics

1997
The quantitative statements of the Griffith theory [1] are based on elasticity theory and are applicable only to those materials that obey Hooke’s law up to the instant of fracture. In confirming his theory, Griffith used glass as the test material because at room temperature glass does follow Hooke’s law to the stress at fracture. Griffith’s work must

Fundamentals of Linear Elastic Fracture Mechanics

2021
Abstract The linear elastic fracture mechanics (LEFM) is the pillar of all fracture mechanics. In this chapter, it is presented in full, with complete derivations and many examples. Griffith's concept of the energy release rates is described, the elastic singular near-tip stress field is derived, and the stress intensity factors are ...

Linear elastic fracture mechanics

1989
In this and the following chapter, the fracture mechanics concepts for the analysis of fracture will be discussed. With these concepts it will be possible to obtain the residual strength diagram and the maximum permissible crack size (Chapter 1). Following the arguments used in Chapter 1, the discussion will be limited to mode I loading (mixed mode ...

Statistical considerations in linear elastic fracture mechanics

Journal of Aircraft, 1975
Critical 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

2016
Solid bodies containing cracks can be characterized by defining a state of stress near a crack tip and the energy balance coupled with fracture. Introducing the Westergaard stress function and will allow the development of a significant stress analysis at the crack tip. These particular functions can be found elsewhere [12].

Linear elastic fracture mechanics of duralumin

Canadian Metallurgical Quarterly, 1969
AbstractOne 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 ...

The Basis of Linear Elastic Fracture Mechanics

2016
In 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.
