Abstract

This project aims to investigate the soft fibre networks using the particle-based method - Discrete Element Method (DEM). I am currently investigating the micromechanical deformation behaviour (in-plane tensile, ZD compression, creping, shearing under compression) of the fibre network for design/redesign of cellulose based fibre products. Typically the fibres are complex in shape with various curl, kink and twist. Therefore I am using linked particles to represent the fibres. Also, such particle-based methods are suitable for parallel computation. To represent a physical size fibre network, a large number of particles are required. Therefore, implementation of parallel computation can save a significant amount of computational time.
