Abstract
In this paper, to investigate the effects on shock waves on cells, shock wave propagating into a cell is analyzed by finite element method with one-dimensional viscoelastie wall, and principal stress and shear stress to estimate mechanical stimulus are obtained. The calculation is intended for suspended and attached cell. The result shows that, a high shear stress is caused by the shock wave in the cell membrane, and the frequency and the maximum shear stress is increased when the rise time of the shock wave is small. In addition, effects of membrane of Young's modulus, dumping constant, Poisson's ratio and cell configuration on the maximum shear stress are confirmed.
