| Abstract: | The viscoelastic materials are used widely with the development of new materials,and the nonlinear dynamic behavior in viscoelastic composite structure is becoming increasingly outstanding and important.The main purpose of this paper is a study of some nonlinear dynamic problems of viscoelastic composite structure under parametric excitation by using the experimental modeling method.The dynamic modeling method based on the theory analysis increases the difficulty on account of the complexity of the constitu... |
