A three-parameter model for fatigue crack growth data analysis
Journal Title: Frattura ed Integrità Strutturale - Year 2012, Vol 6, Issue 21
Abstract
A three-parameters model for the interpolation of fatigue crack propagation data is proposed. It has been validated by a Literature data set obtained by testing 180 M(T) specimens under three different loading levels. In details, it is highlighted that the results of the analysis carried out by means of the proposed model are more smooth and clear than those obtainable using other methods or models. Also, the parameters of the model have been computed and some peculiarities have been picked out.

Growth of inclined fatigue cracks using the biaxial CJP model
The CJP model of crack tip stresses is a modified version of the Williams crack tip stress field which takes account of simplified stress distributions that arise from the presence of a zone of plastic deformatio...
On fatigue behavior of two spring steels. Part I: Wöhler curves and fractured surfaces
Symmetric fatigue in two spring steels is investigated in three groups of specimens. One of the groups (Steel EN10270-1SH/ DIN 17223C – C 0.82%, Mn 0.76%, Si 0.26%) has experienced rotating-bending fatigue in...
