Elastomers, such as silicone, are currently used for many designs of artificial finger and wrist joints because they are inert, durable, flexible and allow the necessary range of movements [1–6]. The disadvantage of these silicone joints is that they fracture in vivo [3,5,7]. In addition, these elastomers are viscoelastic so that their properties may depend on loading frequency. It is then possible that the performance of the joints may be frequency dependent. As a first stage in investigating such effects, we have determined the storage and loss moduli of a medical grade silicone in compression.
