Interaction of single laser generated cavitation bubble with elastic boundary

Though single cavitation bubble interaction with boundaries has been studied for long time [1] [2], little information on materials such as tissues which has small value Yong's modulus is available; the coverage of Yong's modulus of boundary materials is quite narrow, mostly in the range of engineering materials. Furthermore bubbles are often generated by electrodes, which disturbance bubble dynamics. In our experiment, totally 10 types of elastic materials were tested, their Yong's modulus ranges from 4300 Pa to 1880000 Pa, covering most of the human body tissues, such as thoracic aorta (0.04-0.9MPa) [3], femoral artery (1.23-5.5 MPa), articular cartilage (0.43-1.15 MPa) [4], muscle (0.06-0.8 MPa), renal parenchyma(0.06 MPa), abdominal aorta (0.98-1.42 MPa), and cornea (0.3-5 MPa) [5]
