Bending Analysis of Beam Described by Fractional Derivative Kelvin Viscoleastic Model

Based on elastic-viscoelastic correspondence principle,the stress-strain relationship of beam is described by fractional derivative Kelvin viscoelastic model,and the expression of the deflection of fractional derivative Kelvin viscoelastic beam is obtained.The influence of the order of fractional derivative on the bending of viscoelastic beam is analyzed by numerical example.
