Outline of Final Research Achievements

We extended the variational phase-filed fracture model that had assumed the linear elasticity to viscoelastic materials. We investigated non-linear rheology and rupture behaviors of worm-like micelle solutions and dispersions consisting of the micelle solution and polymer particles with several tens micron. Further, we carried out a combined experimental and theoretical investigation on non-monotonous volume change of polymer networks swollen with mixed (two-component) solvent.

Academic Significance and Societal Importance of the Research Achievements

相転移動力学や反応拡散系の記述に用いられる数理的原理―勾配系―に基づいて,複雑なレオロジー特性をもつソフトマターの破壊現象を理解する枠組みの基礎を提示することができた.また,本研究では,溶媒を含む高分子網目系を主たる具体的な研究対象としたがそのレオロジー挙動の理解には溶媒と高分子成分の相対的な運動を理解する必要がある.本研究では,溶媒が2種液体の混合物である場合において従来知られていなかった新たな網目の変形モードを理論的に見出した.これにより,粘着やゴム強度など実用的な破壊問題を,き裂の特異性を意識しない(が,その効果を取り込んだ)モデルによって理解する可能性が開かれた.
