General considerations on the mechanical impedance and on the dynamic stiffness of plates,tated otherwise. This classical plate theory is described for example in LEISSA (1973), NÁDAI and TIMOSHENKO & WOINOWSKY-KRIEGER. The effect of in plane forces on the transverse vibrations and of damping will be disregarded in this paper unless otherwise stated. In what follows we first give a short

Dynamic stiffness of rectangular plates, a, −b ≤ y ≤ b with the boundary conditions corresponding to a free boundary. This problem is considerably more difficult than the corresponding problem for the circular plate, since even the eigenfunctions of the corresponding homogeneous problems have to be written in the form of double series.
