In this study, the effects of random laminate misalignment on the microscopic mechanical behavior of ultrafine plate-fin structures are statistically investigated using the Monte Carlo simulation. For the mechanical analysis, thehomogenization theorybased on unit cell analysis is used. Moreover, the substructure method is introduced into the theory to deal with random laminate misalignment. The present method is applied to the analysis of microscopic stress and strain distribution and their concentration in ultrafine plate-fin structures made of Ni-based alloy with random laminate misalignment. Then, the analysis results are statistically examined using histograms. It is shown that the effects of random laminate misalignment on the mechanical behavior of the plate-fin structures become remarkably strong depending on the loading condition.
