| 摘要： | This paper deals with the numerical implementation of constitutive equation for isotropic viscoelastic asphalt mixture.Firstly the constitutive relations of the generalized three-dimensional Kelvin model are deduced and the discretization of them in deviator and spherical tensor fields are given, respectively.Then the consistent tangent modulus and other coefficient matrix used to calculate the updated stress matrix are achieved by exact linearization of the algorithm.The scheme is highly efficient, since no local iteration procedure is required.The resulting integration algorithm is unconditionally stable and the consistent tangent operator is symmetric.Finally, the proposed numerical method is evaluated with a numerical example and the numerical solutions are in good agreement with the closed-form ones. |
