著者：住隆博，橋本時忠 読み: スミタカヒロ，ハシモトトキタダ題名：慣性キャビテーションの逆解析による軟質材料の粘弾性特性評価発表情報：2020 年度衝撃波シンポジウムキーワード：Soft Material, Viscoelastic Property, High Strain Rate, Inertial Cavitation, Inverse Analysis概要：抄録：From a perspective of medical engineering, viscoelastic properties of soft materials in high strain rate region are highly
important for understanding influences of recent minimally invasive surgical techniques with lasers, ultrasounds, and shock waves on biological tissues. In this study, a new evaluation method of viscoelastic properties of soft materials is presented instead of traditional macroscopic rheometries. The procedure consists of an optical measurement of an inertial micro cavitation inside the soft material induced by a high energy pulsed laser and a numerical solution with respect to an inverse analysis of the equation of motion describing the cavitation dynamics. Polyvinyl alcohol hydrogels (PVA-H) with different mass concentrations were employed as test materials and evaluated to validate the proposed microscopic rheological methodology.英語フィールド
