The dynamic behaviours of a viscoelastic two-member truss system, subjected to sinusoidal excitation, are investigated in this paper.The viscoelastic material was assumed to obey the fractional calculus constitutive laws.The dynamic equation and the numerical computation scheme suited for this nonlinear fractional viscoelastic system are deducted;the dynamic behaviours are investigated by means of numerical methods of nonlinear dynamics, such as time domain, phase diagram, Poincare map, and so on.It is found that there are plenty of dynamical phenomena, such as periodicity, bifurcation, quasi-periodicity and chaos in the system and the dynamical character is greatly inflected by the varying of material parameters.
