Abstract
Linearly elastic behaviour of paper is described by four independent in — plane constants. Elastic constants depend on probability density functions for length and orientation and also on a coupling network parameter between fibers. It is shown here that the ratio of machine to cross direction Young’s moduli determines the fibre orientation parameter. All constants then simply depend on one network parameter and one orientation parameter.
We can describe the behaviour of a thin non-linear orthotropic plate using an asymptotic expansion method. We apply in this paper the theory proposed by Johnson to an assumed form of the elastic strain energy function. Linear or non-linear biaxial behaviour of such a material is then obtained from ordinary tests.
