Abstract
Viscoelastic materials are often used for solving engineering vibration and noise control problems. It is difficult to examine dynamic properties under high or very low frequency. Thus composite curves of dynamic properties are constructed by applying frequency-temperature reducibility to the experimental data. Much time and labor is needed for constructing composite curves of dynamic properties by manual. Therefore computer programs are needed to construct composite curves of dynamic properties. In this paper three kinds of algorithm for determining both shift and reducing factor are discussed.
