    Notes: Abstract— A number of fretting fatigue tests were carried out on CMV steel and INCO 718 alloys under closely controlled experimental conditions. A fracture mechanics-based lifing model was developed and the Paris Law employed to predict fatigue lives under a range of experimental conditions. An effective initial flaw size was used to describe initiation and early propagation of cracks. This approach was found to give good predictions of fatigue life of specimens for different values of bulk stress under the same fretting load.

    The effect of a corner radius on an asymptotic solution to the fretting of complete contacts including the plastic process zone (2003)

    Fatigue & fracture of engineering materials & structures 26 (2003), S. 0

    Notes: An asymptotic elastic solution provides a good way of encapsulating the behaviour of the process zone at the edge of a complete contact. In this paper we examine the effect of a finite edge radius on the validity of such an approach, and provide clear recommendations on the tolerable edge radius if the asymptotic approach is to remain viable.

    INITIATION AND GROWTH OF FRETTING FATIGUE CRACKS IN THE PARTIAL SLIP REGIME (1989)
    Oxford, UK : Blackwell Publishing Ltd
    Fatigue & fracture of engineering materials & structures 12 (1989), S. 0

    Notes: Abstract— —Recent work addressing the problems of fretting fatigue crack initiation and propagation under a carefully controlled axi-symmetric Hertzian contact is described. Both experimental work, enabling the fretting damage, sites of initiation, and crack trajectory to be viewed, and theoretical work, permitting a prediction of those processes are presented. Good correlation between the two strands of work is found. In particular, the initiation criterion proposed by Ruiz, Boddington and Chen for a very different geometry is found to work well, and would seem to indicate its potential as a design tool.

    Crack initiation: the choice of tests available to calibrate Dang Van's criterion (2002)
    Oxford, UK : Blackwell Science Ltd
    Fatigue & fracture of engineering materials & structures 25 (2002), S. 0 
    Details
    ISSN: 1460-2695
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Dang Van has proposed a method for predicting fatigue life under high cycle fatigue conditions, where the time for a crack to propagate to the critical length is negligible compared to the time it takes for it to initiate. His argument is that if shakedown is achieved at the grain level, a crack will never initiate. Since the exact stress state at the grain level is very difficult to quantify, the determination of the fatigue limit is achieved using calibration experiments. These experiments need not be restricted to bending and torsion as is common practice. Indeed, any form of specimen geometry and loading path may be used to estimate fatigue life. The comparison of many such tests can not only lead to a more accurate definition of the fatigue limit, but also indicates the suitability of the criterion. Moreover, by ensuring that calibration and specimen data lie close together on the fatigue locus, a better prediction of initiation conditions is achieved.

    Modelling of growth of three-dimensional cracks by a continuous distribution of dislocation loops (1997)
    Springer
    Computational mechanics 19 (1997), S. 538-544 
    Details
    ISSN: 1432-0924
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract This paper is concerned with a numerical simulation of growth of fatigue cracks in a three-dimensional geometry. A continuous distribution of infinitesimal dislocation loops is employed to model the crack faces, so that the crack problem can be formulated as a set of singular integral equations. A numerical procedure based on an analytical treatment of the associated finite part integral is developed to solve the singular integral equations. The Paris law is then used to predict the rate of crack growth, so that the evolution of the crack shape under fatigue can be traced by a step-by-step algorithm. Various crack growth problems, e.g., the growth of a subsurface crack in a surface treated specimen, are analyzed using the technique, providing new data for several cracks of practical interest.

    The influence of elastic mismatch between indenter and substrate on Hertzian fracture (1994)
    Springer
    Journal of materials science 29 (1994), S. 2860-2866 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract This paper is concerned with indentation testing of brittle materials. It is shown that a mismatch of elastic constants between the indenter and component being tested has a profound influence on the stress state induced. It is shown that the development of surface flaws into cracks is severely impeded if the indenter is more rigid than the substrate and vice versa. A quantitative assessment of this phenomenon, in terms of both the contact stress field generated and the stress intensity factor experienced by defects, is given. This permits a more precise determination of either the fracture toughness or the surface flaw distribution to be made.

    Partial closure and frictional slip of 3-D cracks (1993)
    Springer
    International journal of fracture 63 (1993), S. 89-99 
    Details
    ISSN: 1573-2673
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The effects of partial closure and frictional slip of three-dimensional cracks on the stress intensity factors are studied using the eigenstrain method. The formulation, based on the correct modelling of the boundary conditions on the crack faces, is presented separately for partial closure and frictional slip, and applied to two simpler cases: partial closure of a surface-breaking crack normal to the free surface and under a residual stress field; and frictional slip of a completely closed crack under normal and shear tractions. The evolution of crack closure with the increase of crack depth and its influence on the stress intensity factor are examined and compared with a simple model for the first problem. the effect of coefficient of friction between crack faces on the stress intensity factors is investigated for the second problem.

    Solution of cracks developing from stress raisers, in finite bodies, by a hybrid dislocation density/BEM approach (1996)
    Springer
    International journal of fracture 77 (1996), S. 175-184

    ISSN: 1573-2673

    Notes: Abstract A method is described for determining crack tip stress intensity factors for cracks growing from stress raisers such as voids or inclusions, but in bodies having finite external dimensions. This is based on a combination of the dislocation density approach, where the influence of the stress raiser is automatically included, and the boundary element method, which is used to account for the presence of the remote surfaces.

    Notes: Abstract An analysis of a crack lying along an interface between two elastically dissimilar quarter-planes, and breaking the free surface is given. The method of distributed dislocations is employed and the nominal stress field is taken to be uniform along the length of the line of the crack. Models for crack tip behaviour are discussed and it is shown that a simplified quadrature can be used to extract the crack extension force for cases where small-scale contact obtains. Values of the crack extension force are given, displayed on the α, β diagram.
