Large deformation winding models
Abstract
Almost all winding models incorporate the assumption of small linear deformations and strain in development. As such these models treat the addition of a layer of web to a winding roll with linear analysis using linear strain theory. Some webs such as tissues and nonwovens are highly extensible in-plane and highly compressible through their thickness. Do the models which assume small deformations apply to these web materials? In this paper a winding model developed using large deformation theory will be presented. The output of this model will be compared with the results of winding tests done in the laboratory and with the outputs of models which employ small deformation theory to answer the question posed.
