Analysis of Stress Wave as Mechanical Stimulus to a Cell by Shock Waves

Abstract

In this paper, an underwater shock wave propagating into a cell is analyzed by finite element method, The cell is attached on the wall in water. The fluid part and the cell part are coupled with one-dimensional viscoelastic wall. The result shows that high shear stress is generated by the shock wave in the cell membrane. The frequency of shear stress and the maximum shear stress increase when the rise time of the shock wave is short.
