The oscillation of a thin blade immersed in a viscous fluid has received considerable attention recently due to its importance in technological applications such as the atomic force microscope and microelectromechanical systems. In this article, we consider the general case of a flexible thin blade executing spatially varying small amplitude oscillations in a viscous fluid. Exact analytical solutions for the three-dimensional flow field and hydrodynamic load are derived for both normal and torsional oscillations of arbitrary wave number. This contrasts previous investigations that focus exclusively on the complementary rigid-blade problem, which is two-dimensional, and rely on computational techniques.

- This definition of the Reynolds number differs from Refs. 10,11,12,13,14,15 by a factor of 4, and is preferred in the present context since it appears naturally in the final exact solutions [see Eqs. (22), (37)]. The convention adopted for the Reynolds number also conforms with Ref. 16. The Reynolds number is often associated with the nonlinear convective inertial term in the Navier-Stokes equation. This latter convention has not been adopted here.
