| Abstract: |
| This paper investigates the coupled motion of a viscous fluid and an elastic material interface with zero thickness.By using the immersed interface method and time-stepping method,semi-Lagrange discrete method respectively,the decomposed Stokes part and regular part are solved,and the general calculating method of the second-order PDE related to the coupled motion is obtained.Furthermore,we improve the results of[14,15,18]. |
