Steady State Response of Infinite Elastic Beam on Viscoelastic Ground Described by Fractional Derivative Model

摘要：

Soil is regard as viscoelastic material, and the stress-strain relationship of soil is described by fractional derivative Kelvin viscoelastic model, and obtained the expressions of the foundation reaction force and displacement. The motion control equations of the elastic beam with infinite length on foundation described by fractional derivative model are established and the steady response of the beam is investigated. The influence of the order of fractional differential operator on the steady-state response of elastic beam with infinite length is analyzed by numerical example, and some useful results are obtained.
