A New Method for Performance Measurement of Printing Paper

摘要

A new method is proposed to research on the performance measurement of printing paper. The constitutive equation of a viscoelastic model of printing paper is obtained by means of Laplace Transform(LT), which can be used to analyze creep, recovery and relaxation characteristics. The analytical expressions describing the relation stress-strain to time are deduced. The results indicate that the stress–strain constitutive equation is nonlinear, which belongs to material non-linearity question.
