The fatigue can occur by varying stress caused by varying load during operation. Subsequently, it is important to consider the uncertainty in the finite element analysis. Monte Carlo simulation is widely used to solve problems that take the uncertainty of the load condition into consideration. However, dynamic analysis takes longer time than linear static analysis. Hence, in this study, fast dynamic analysis using block second order Arnoldi method, which is one of the techniques of the model order reduction, is applied to the Monte Carlo simulation. Its accuracy and usefulness are shown through comparison with the analysis by explicit method.
