%T Are the Paris' law parameters dependent on each other?
%U http://eprints.imtlucca.it/1948/
%X The question about the existence of a correlation between the parameters C and m of the Paris’ law is  re-examined in this paper. According to dimensional analysis and incomplete self-similarity concepts  applied to the linear range of fatigue crack growth, a power-law asymptotic representation relating the  parameter C to m and to the governing variables of the fatigue phenomenon is derived. Then, from the  observation that the Griffith-Irwin instability must coincide with the Paris’ instability at the onset of rapid  crack growth, the exponents entering this correlation are determined. A fair good agreement is found  between the proposed correlation and the experimental data concerning Aluminium, Titanium and steel  alloys
