SOME TEXTILE APPLICATIONS OF FINITE-ELEMENT ANALYSIS - PART II - FINITE-ELEMENTS FOR YARN MECHANICS

The concepts of modal decomposition developed in an earlier paper are used to produce a three-dimensional element for aligned fibre assembli es. The element degrees of freedom are introduced and the chosen mode shapes of the element demonstrated, The finite element is tested by us ing simple material-property assumptions, and the element is verified against a theoretical model of the twisting of a single fibre about a solid core, The element is then verified qualitatively by modelling re alistic yarn situations, and the resultant deformation plots are prese nted.
