- Abstract:
-
The characteristics of differential and integral viscoelastic constitutive equations are compared, and the equivalence of the two is proved. The selected integral viscoelastic constitutive equation is simplified and corrected according to the characteristics of injection molding, and its recursive formula is derived, which is convenient for the derivation and program development of the finite element calculation formula under the viscoelastic constitutive relationship, and provides a theoretical basis for the calculation of residual stress and warpage deformation analysis of plastic parts in injection mold CAE
