In this paper we propose an energy-based criterion for life-prediction of fatigue crack initiation via a 3D, elastically anisotropic FE model for cyclic deformation and hardening of face-centred cubic (FCC) materials. © CIMNE, 2007.

Olver AV, Dini D, 2007, Roughness in lubricated rolling contact: the dry contact limit, P I MECH ENG J-J ENG, Vol: 221, Pages: 787-791, ISSN: 1350-6501

A difficulty with the standard fast Fourier transform (FFT) perturbation model of roughness in lubricated rolling contacts is that it does not necessarily converge towards the elastic case as the film thickness is reduced; rather it leads to a situation in which all the roughness is completely flattened. This is rarely the case for real engineering surfaces.Here, it is shown that this difficulty can be avoided by carrying out a Fourier transform of the elastostatically flattened roughness and using the resulting (complex) amplitude as the low-film thickness limit of each Fourier component in the elastohydrodynamic lubrication (EHL) analysis.Results give a plausible convergence to the elastostatic solution, which is nevertheless consistent with the expected near-full-film EHL behaviour and which becomes identical to the earlier model for roughness that, statically, can be fully flattened. As expected, hydrodynamic action persists at the finest scale, even for very thin films.

In a previous article, this group described the principles involved in the development of bioengineered skin equivalents that held out much promise. This article has examined some of the uses of such products in treating venous ulcers, diabetic foot ulcers, and skin diseases leaving skin wounds. Data encouraging the use of such products in certain indications are available. The costs of using such products are also appreciated.

Components subject to fretting experience a peculiar combination of loading conditions, where contact and classical fatigue interact intricately to produce failure. As a consequence, the prediction of fretting fatigue limit curves poses a challenge, in part due to the large number of parameters governing the phenomenon. This poses an obstacle to formulating efficient predictive approaches. We demonstrate that these difficulties can be overcome successfully by means of a combination of experimental and computational approaches. Our analysis relies on various experimental data from Hertzian and 'flat and rounded' contact pad specimens and different calculation procedures developed previously, which resulted in fretting threshold curves for specific loading conditions. The derivation of such thresholds is however rather lengthy, so that for the purposes of formulating design rules a more efficient 'master curve' approach is proposed. This paper presents comprehensive results on the application of an efficient and concise functional description of the fretting fatigue threshold curves based on the use of a 'multi-scaling power law'. The predictions encompass all of the results obtained for different loading conditions by the stress-based approach and by short crack arrest methodology.
