【 摘 要 】

The Supplement 1 to the "Guide to the expression of uncertainty in measurement" indicates the Monte Carlo method for calculating the expanded measurement uncertainty. The objective of this work is to compare the measurement uncertainty values obtained via Monte Carlo method through two commercial softwares (Matlab®and Crystal Ball®) for the parameter 'adjusted strain', obtained from fatigue tests. Simulations were carried out using different number of iterations and different levels of confidence. The results showed that there are short differences between the measurement uncertainty values generated by different software.
