The stiffness of bonded rubber blocks under small compressive deformations has been studied extensively. A recent review deals with the problem in connection with the use of elastomeric laminaes as bridge bearings. However, previous studies have been mainly concerned with a flat rubber block bonded between two flat rigid plates. An approximate treatment is given here for the stiffness of a rubber layer bonded between two opposed curved rigid surfaces, cylindrical or spherical in shape. The predictions of the theoretical treatment are then compared with measured values of compressive stiffness for various initial separations and hence rubber layer thicknesses of the two rigid surfaces, relative to their diameter.
