【Abstract】 This paper deals with the dynamic rheological behaviour of carpets under harmonic compressive stresses. The effects of the circle frequency of the load force on the loss of mechanical energy and the loss angle and the accumulation of the largest elastic strain energy were analyzed. Loss performances of different kinds of carpets were compared. The results show that the loss of mechanical energy, the loss angle and the accumulation of the large elastic strain energy can be used to evaluate covering properties of carpets.更多还原
