Abstract
The mechanical behavior of silicone sealants has been examined at six different rates of extension and at three temperatures. The rates of extension used were chosen to cover the usual laboratory testing rates and the highest rates of movement occurring in expansion joints of buildings. The latter were estimated and experimentally determined. The samples used were model representations of sealant beads as used in the joints of buildings. The possibility of applying theoretical information to the practical model sample, which had a complicated stress field, was investigated. A single curve could be constructed from the individual tensile curves obtained at varying rates at each temperature.
