INVERSE ANALYSIS OF PSEUDO STATIC DISPLACEMENT FOR INHOMOGENEOUS VISCOELASTIC MEDIA
非均质粘弹性介质的准静态位移反演

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.
