摘      要：正In this paper,an efficient way to treat the interaction between an incompressible viscous fluid and an elastic body in a fully coupled arbitrary Lagrangian-Eulerian formulation is presented. The constitutive relations for both fluid and flexible body are unified into the same form,and flexible body part is imagined as a special fluid which can have the same form of governing equations as the Navier-Stokes equations for fluid *** example of an incompressible viscous channel flow around an elastic plate attached on the solid channel wall which results in self-induced oscillations of the structure is provided to show the efficiency of the presented method for detailed simulations of incompressible viscous flows interacting with flexible structures.
