Abstract: In this project, the effects of moisture on the mechanical behavior of paperboard has been investigated. In particular, experiments under controlled environmental conditions have been performed do determine the effects of moister content on the MD and CD initial elastic moduli, the Poission's ratios, the initial shear modulus, and the shapes of the MD and CD uniaxial stress-strain curves. These results were then utilized to calculate the input parameters fo a set of biaxial nonlinear elastic stress-strain relations for paperboard. The moisture dependence of the material constants and of the strain energy density function utilized within the nonlinear model have been determined.

Keywords: moisture; paperboard; modulus; shear modulus; Poisson’s ratio; biaxial test; strain energy density
