| Outline of Final Research Achievements |
First, micro-macro relations were derived for developing a homogenized viscoplastic constitutive equation of anisotropic open-porous bodies subjected to pore pressure. Second, using the derived micro-macro relations, the effect of micro-viscoplasticity and pore pressure on the homogenized viscoplastic behavior was theoretically investigated. Third, based on the theoretical findings, a homogenized viscoplastic equation was developed. Then, the resulting constitutive equation was verified by performing finite element homogenization analysis of unit cells of plate-fin structures and thick perforated plates.
