Q. Behaviour of elastomeric bearings ?

In order to carry out successful design and installation of elastomeric bearings, it is necessary to understand the behaviour of elastomeric bearings  against various imposed loads. The elastomer being practically incompressible, the total volume of the pad in loaded and unloaded conditions remains unchanged. Therefore, under the action of a compressive load, a plain elastomeric pad with no friction on its top and bottom surfaces, flattens and expands laterally as shown in Fig.
