Abstract : Damped lateral vibration in an axially creeping beam with random material parameters is considered. The temperature and imperfection density and as a result two inelastic material parameters are random functions of the distance along the neutral axis. It is assumed that the material of the beam is governed by a nonlinear Maxwell model, and that the initial tensile stress is much greater than the increment of stress caused by the oscillation so that a perturbation technique may be employed. Two special cases are fully analyzed: the random parameters are random processes which are only slightly random, and the random parameters are random variables which are largely random. (Author)
