Abstract

Numerical studies of fiber networks and experiments on wet paper show that tensile force relaxes linearly as a function of logarithmic time. Relaxation rate is faster for wet than dry paper. Simulated permanent deformation after relaxation is clearly higher than that measured in wet paper.
