摘要：

The aim of the present paper is application of a differential operator of variable order in constitutive relations for viscoelastic materials. This operator is used for studying the vibrations of a one-degree-of-freedom oscillator, in which the viscoelastic deformation is governed by a servo order function. A method for numerical determination of the eigen-frequency of the fractional differential equation is proposed. (C) 2004 Elsevier B.V. All rights reserved.
