TENSILE-STRENGTH OF PAPER - A SIMULATION STUDY

This paper simulates the effect of distributions of pulp fibre propert ies on tensile strength using a theory created in a recent article. Di screte distributions with one and two values, and continuous distribut ions are used. Simulations are performed for sheets with uniform fibre orientation, as well as random and eccentric fibre orientation distri butions. The effect of fibre orientation distribution on tensile stren gth differs in its effect on Young's modulus. Increased variation. in pulp fibre properties considerably decreases tensile strength. A group of fibres with specified properties and orientation distribution embe dded in a medium that elongates uniformly produces a load-strain curve of almost universal shape.
