The staircase method is often used to determine the fatigue limit of components. Several evaluation techniques are available for these fatigue tests. Here, artificial" fatigue tests are generated and evaluated using the Monte Carlo simulation statistical tool to compare the accuracy of these methods. Monte Carlo simulations are also used to compare the performances of these methods for estimating the fatigue limit for 50% probability of failure and the standard deviation for the log-normal distribution. This work demonstrates the use of statistical testing for evaluating experimental results in comparison with quality standards.
