Abstract

It is shown in this paper that the in-plane shear modulus and Poisson's ratio of paper can be predicted with reasonable accuracy if the Young's moduli of the paper in the machine and cross directions are known. The experimentally observed invariance of in-plane shear modulus with respect to sheet orientation is utilised to determine a relationship between the first two coefficients in a Fourier series expansion of the fibre distribution. Using Cox's classic model for paper this permits the sought-after relationships to be determined.
