This paper describes the analysis of coupling oscillation problems between the cell deformations and flow induced by propagating underwater shock waves. Actually the cells including cavitation bubbles are destroyed by using under water shock waves when the new shock wave DDS (Drug Delivery Systems) method is used. For this analysis, the capsules are modeled as liquid droplet including gas bubbles. By computation using ALE (Arbitrary Lagragian-Eulerian) Method, the coupling oscillation and bubble deformation process are analyzed. The results show that the effects of the acoustic impedance of the fluid media in water and motion of the shell is large for the deformation process.
