The stress intensity factor of cylindrical cracks

International Journal of Engineering Science, 1995
Abstract An analytical expression for the stress intensity factor K 1 of a cylindrical crack situated at a fiber-matrix interface has been developed. A model of the crack as a pile-up of Somigliana ring dislocations is replaced by an equivalent pair of superdislocations which leads to the analytical solution.

Summary of Stress-Intensity Factors

1996
Abstract The stress-intensity concept is based on the parameter that quantifies the stresses at a crack tip. This article summarizes some stress-intensity factors for various crack geometries commonly found in structural components. Through-the-thickness cracks may be located in the middle of a plate; at the edge of a plate; or at the ...

Stress intensity factors for interacting cracks

Engineering Fracture Mechanics, 1987
Abstract Experimental stress intensity factors (SIFs) for two interacting straight cracks in plane-homogeneous regions were determined. Photoelastic data were collected from digitally sharpened isochromatic fringe patterns by using a digital image analysis system. SIFs were extracted by using the field equations derived from Williams' stress function.

Dynamic Stress Intensity Factor

2003
An infinite strip of height 2h with a semi-infinite crack is rigidly clamped along its upper and lower faces at y = ± h (Figure 1). The upper and lower faces are moved in the positive and negative y-direction over distances u0, respectively. Determine the dynamic stress intensity factor K(t) during steady state crack propagation.

A note on cylinder stress-intensity factors

International Journal of Pressure Vessels and Piping, 1975
Abstract A comparison is made between Shannon's finite element K results for internally pressurised thick-walled cylinders with one and two radial cracks and Bowie and Freese's mapping-collocation results for the same geometries. The comparison is good except for shallow cracks relative to the cylinder wall thickness. Based on the nature of the

Calculate the Stress Intensity Factor by ANSYS

Advanced Materials Research, 2013
Mode I crack for an example, this paper conducts the introduction and analysis of the use of finite element software ANSYS to calculate the stress intensity factor approaches. Compared the stress intensity factor values with the analytic solution, it shows that the finite element method to calculate the stress intensity factor has a very high precision,

Bounding functions for stress intensity factors [PDF]

International Journal of Fracture, 1984
Functions for determining upper and lower bounds on opening mode stress intensity factors are derived. These are used to determine bounding functions for a radial crack at the edge of a hole and for a crack at the edge of a finite width strip. It is shown that, for the limiting case of vanishingly small cracks, these bounding functions approach a value

Stress intensity factors of welded joints

Engineering Fracture Mechanics, 1993
Abstract Stress intensity factors of welded joints have been calculated for a variety of joint types and dimensional parameters. The following have been considered: non-loadcarrying transverse and longitudinal attachments, cruciform joints with K-butt and with fillet welds, and lap joints with fillet welds.

Stress intensity factor of a patched crack

International Journal of Solids and Structures, 1997
Stress intensity factor for an isotropic cracked plate with orthotropic patch reinforcement is calculated by the finite element method. Three-dimensional (3-D) elements are employed in the present study with the help of an adhesive element analysis performed in advance.

Stress intensity factors for plates in flexure

The Aeronautical Journal, 1984
SummaryA method for determining stress intensity factors for cracked plates is proposed. The method uses a generalisation of Westergaard's stress functions to describe the stress intensity at the crack. Eigenfunctions of angular regions are used to satisfy the boundary conditions.
