| Abstract: | An explicit relation between constitutive parameters and qusi_static displacement of viscoelasticity is derived under a kind of boundary condition, and an iterative form of optimized identification is presented.Viscoelastic constitutive models are identified from a two order differential model, and effects of information errors on results of inverse analysis are discussed. |
