DescriptionDetermining optimum distribution of fiber through rational design of corrugated fiberboard could result in significant reductions in fiber required to meet end-use conditions, with subsequent reductions in price pressure and extension of the softwood timber supply. A theory of thin plates under large deformations is developed that is both kinematically and physically nonlinear. This theory is used to analyze the strength of a singlewall fiberboard element which modeled as a composite plate structure. Either an elastic-type instability or a compression failure mode is allowed. The results of this analysis used to explain how to adjust facing and corrugating medium thicknesses to maximize the edgewise compression strength per board weight.
