Role of multiaxial stress state in the hydrogen-assisted rolling-contact fatigue in bearings for wind turbines	2015	10	.pdf	application/pdf	5322	208	54	According to previous equations, hydrogen diffusion is driven by: (i) the negative gradient of hydrogen concentration (in the classical Fick´s sense); (ii) the positive gradient of hydrostatic stress; (iii) the positive gradient of hydrogen solubility, the latter is one-to-one related to the gradient of equivalent plastic strain so that the plastic strain gradient can be analysed instead of the hydrogen solubility gradient. Figure 6: Distribution of hydrostatic stress: (a) 3D view of the contacting plane and (b) radial distribution for diverse circumferential coordinate . J. Toribio et alii, Frattura ed Integrità Strutturale, 33 (2015) 434-443; DOI: 10.3221/IGF-ESIS.33.48 439 For completing the analysis of hydrogen diffusion and accumulation on the rod during life in service, the information obtained from the estimation of hydrogen concentration in the radial direction [2,3] can be completed by a discussion of the implications of diffusion in the circumferential direction.	cache/fis-1457.pdf	txt/fis-1457.txt
