| Outline of Final Research Achievements |
The purpose of this research is to develop a homogenization numerical simulation methods for mechanical characteristics, such as stiffness and strength of microcellular foam materials which contains microscale air voids.
Mechanical characteristics of foam and matrix materials were evaluated by mechanical loading tests of microcellular foam. A 3-dimensional homogenized finite element analysis program which is possible to apply the periodic boundary condition of microstructures was developed. Proposed analysis method is possible to predict the stiffens in finite strain region considering the microstructures.
