Calculation and Program Processing of Doubtful Values in Material Fatigue Test Data

The judgment principle for doubtful values in material fatigue test data was described and the application software was developed for doubtful value calculation. Development language was Visual C#. The software could be gotten doubtful values, average values and standard deviation and so on. The doubtful values should be located in the sample and showed. The software functions and calculation accuracy had been verified via the actual test data. The results showed that the software was conveniences and flexible, and improved the efficiency for dealing with material fatigue test data, and also could be used to deal with other test data.
