In this study, the inelastic analysis of an ultra fine plate-fin is performed based on a homogenization theory. To this end, the homogenization theory of non-linear time-dependent materials, which was developed by the present authors, is applied to the analysis. Moreover, utilizing the point-symmetric structure of plate-fin, the domain of analysis is reduced by half. Then, the elastic-creep deformation of ultra fine plate-fin made of Hastelloy X under uniaxial tension or simple shear at 950℃ is analyzed by using the homogenization theory. It is thus shown that the macroscopic elastic-creep behavior of plate-fin exhibits significant anisotropy. It is also shown that the marked variation of macroscopic bulk strain of plate-fin is caused by the loading in the staking direction.
