| 摘 要： | 比较了微分型、积分型粘弹性本构方程的特点，并对二者的等价性进行了证明．对选用的积分型粘弹性本构方程，根据注塑成型的特点进行简化、修正，并推导了其递推公式，便于粘弹性本构关系下有限元计算公式的推导和程序研制，为注塑模ＣＡＥ中塑件残余应力计算和翘曲变形分析提供了理论基础．

| Abstract: | The comparison of difference and integrate equations of viscoelastic constitutions are discussed in this paper,and then the equivalence proof of two constitution equations is given. According to the features of injection molding, two-dimension thermoviscoelastic integrate models have been simplified and modified to reduce storage space of hereditary integral items, and to obtain the recurrence formula which is helpful to FEM program code,which provide theory basis for calculation of residual stress and warping analysis of CAE for injection molding. |
