Fatigue Equation Parameters Relationships

Abstract

Substantial amounts of data concerning the fatigue performance tests are presented.These data contain the information about results that are expressed by means of the fatife equation parameters Different fatigue tests are included using different types of mixes. The collected information was not similar in all aspeets.Some studies included variables ,which were not considered by other.The defferent representation of the fatigue equation makes it necessary to find the relations between the parameters of these different equations in order to study all the data belong to the same population .The Kolmogorov-Smirnov test for goodness of fit was adopted for this purpose.
