Purpose of this study is to propose a identification technique of nonlinear viscoelastic model considering the continuous unsymmetrical viscosity through the change of direction and magnitude of the deformation velocity of viscous element. In this paper, the model is represented by the nonlinear Voigt model which is composed of both polynomials of the viscous element and elastic element. For such a characteristics of the viscosity to be realized, the following property is employed : the sign of odd-order terms contained in the polynomial of viscous element depends on the direction of deformation velocity, and that of even-order terms does not. By comparing the identification accuracy of transient response of this model with those of symmetrical viscosity model and discontinuous unsymmetrical viscosity model by relative standard error, this model was evaluated as valid for a wide intensity range of shock loads.
