Determining the Accuracy of the Life Determination Analysis for Low Carbon Steel

Abstract:

The objective of this paper is to obtain fatigue properties of API X65 steel using the stress life (S-N) approached. In this method S-N curve was established by relating the applied load and the number of cycles to failure. The sets of data were successfully constructed within the range of high and low cycle domains. The fully reversed loading was employed to generate the most severe damage condition. The experiment data lies approximately within correlation boundaries of 1:2 and 2:1. The mean square error was performed to evaluate the goodness of experiment to the simulated data. Therefore, with a 21% of accuracy it was concluded the presented data taken from actual measurements can be used for life prediction of X65 steel.
