History-dependent dimensional stability of paper

摘要: History-dependent dimensional behavior of paper has been formulated within the framework general linear theory viscoelasticity and classical lamination theory. The effect drying history papermaking process was incorporated by introducing “residual stress” in reference configuration which taken at final stage this study. This permits us to account for complex form changes converting end use processes. In order determine prediction performance computer simulation model developed, in-plane out-of-plane responses under cyclic humidity were predicted on basis hygroviscoelastic data paper. examples demonstrated typical irreversible both change curvature (curl). code can easily deal with non-uniform distribution 1) anisotropic viscoelastic properties, 2) hygrothermal 3) moisture temperature through thickness.
