摘要
从有限元及优化方法出发，给出非均质粘弹性介质的分阶反演公式，对粘弹性本构模式的识别作了初步探讨。
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.
