| Outline of Final Research Achievements |
In this study, we formulated a method of two-scale analysis to predict unsteady thermo-mechanically coupled behaviors in the microstructure of polymer based composite and to evaluate coupled thermo-mechanical macroscopic properties. As a result, the verification for the thermo-mechanically coupled problem of thermo-hyperelastic composite demonstrated that our proposed method can evaluate unsteady two-scale thermo-mechanically coupled behaviors of composites accurately.

本提案手法では，「非定常」な複合材料の熱・機械連成挙動を微視・巨視構造レベル双方で高精度に予測することが可能である．そのため，微視構造レベルで局所的に温度が蓄積し，それによる残留応力が問題となる充填ゴムや繊維強化樹脂の強度評価を高精度に実施することが可能である．また，トポロジー最適化手法との組み合わせによってこれらの弱点を克服するような微視構造のデザインも可能になる．したがって，本手法は実用面においても極めて有用であるといえる．
