Abstract:
Pulp fibres are a part of the paper fibre network and contribute to its non‐linear rate‐dependent behaviour [1]. An appropriate material model helps to quantify and understand these mechanisms, which are highly relevant to industry. The development of the constitutive equations is based on cyclic uniaxial tension tests [2] . For that first a one dimensional viscoelastic, viscoplastic model was designed to fit experimental data. This one dimensional model is then ported to a three dimensional formulation with the logarithmic strain framework [3]. The investigation shows that pulp fibres have a distinct plastic behaviour, which could be the cause of the non‐linear behaviour on the macroscopic level of the network.
