1	Investigation of wet paper viscoelastic structural properties Smith, Tyler Lincoln 09 December 2005 (has links) The thesis studies the relationship between inter-fiber forces present within a cellulose fiber web under varying external conditions. It particularly concentrates on the degree of fiber to fiber bonding and fiber entanglement as a function of moisture content. Finite element analysis of the fiber bonding is used in conjunction with the experimental results to analyze and explain the inter-fiber behaviors taking place within a sheet.

2	Investigation of wet paper cohesive properties Guerrero Serrato, Alexander 09 July 2008 (has links) Wet web paper cohesive properties behave in a similar way than tensile strength properties. The result was obtained using an unique apparatus developed by the IPST, which allows the cohesive strength determination for different wet web solids content. With the results a linear relation can be established between the cohesive strength index (obtained with the splitting apparatus) and the tensile strength index (obtained with the Instron). The splitting apparatus results can be used to calculate strain based on the work of Osterberg.
