Abstract

Abstract

The equations of motion governing the quasi-static and dynamical behavior of a viscoelastic Timoshenko beam are derived.The viscoelastic material is assumed to obey a three-dimensional fractional derivative constitutive relation.The quasi-static behavior of the viscoelastic Timoshenko beam under step loading is analyzed and the analytical solution is obtained.The influence of material paraeters on the deflection is investigated.The dynamical response of the viscoelastic Timoshenko beam subjected to a periodic excitation is studied by means of mode shape functions.And the effect of both transverse shear and rotational inertia on the vibration of the beam is discussed.
