is essential. However, mechanical characterization of viscoelastic materials at high strain-rates using a rheometer is difficult due to material failure during the test. To measure accurately the viscoelastic properties of soft materials at high strain-rates, we sug- gest physical property evaluation method of viscoelastic material using laser-induced bubble. We obtained single cavitation bub- ble dynamics generated by Nd: YAG laser radiation within PVA-H using a high-speed camera. Furthermore, we performed nu- merical analysis relate to an inverse problem of Rayleigh-Plesset equation for the measured microbubble oscillation.英語フィールド
