| Abstract: | Based on the finite element and optimization methods, this paper develops the formulae of inverse analysis for inhomogeneous viscoelastic media. A preliminary discussion about identification of viscoelastic constitutive models is made, the effect of information error is considered, and some numerical examples are exhibited. |
