| Abstract: | An explicit relation between constitutive porameters and quasi-static displacementof viscoelasticity is derived under a kind of boundary condition,and an iterative form of optimixed idenification is presented .Viscoelastic constitutive models are identifiedfrom a two order differential model ,and effects of information errors on results of inverse analysis are discussed. |
| Keywords: | viscoelasticity constitutive model static displacement inverseanalysis |
