This paper describes numerical simulation about the shape and its drag of an elastic body deformed under fluid dynamic force. The simulation is carried out with coupling the incompressible Navier-Stokes equations and the equations of motion of the elastic body. The equations of motion is formulated for elastic shell model which is composed of material particles connected with elastic springs and dampers. Relation between the shape and its drag force in response to the fluid dynamic force is investigated under the constraint for fixing the volume and the gravity center of the elastic body. While the viscous drag decreases with the deforming of elastic body under fluid dynamic force, the pressure drag further increases so that the total drag also increases.
