For this purpose, we develop a finite element model accounting for the fluid-structure interaction and the structural anisotropy of each layer. Two types of fins have been tested by comparing their eigenfrequencies. A dynamical situation has been simulated by imposing a translation (heaving) and a rotation (pitching) motions at the end of the fin, using in some sense a relative frame attached to the ankle joint. Thrust, lift and pitching moment are evaluated and compared for the two types of fins.
