1. Introduction

Postdoc (3 years) on finite element modelling of textile materials and processes

We are looking for a postdoctoral researcher for a research project on textile modelling. In this project, the main purpose is to develop a multi-scale textile modelling framework that allows accurate simulation of textile manufacturing processes such as yarn unwinding from a bobbin, weft insertion during weaving, stitching and tufting. This framework is implemented using finite element modelling as well as virtual fibre modelling. Key here are the dynamics of these systems as most textile production happens at high speeds.

Compressive Strength of Fabric??

Choose a channel featured in the header of iMechanica: 

I am trying to model a rubber impregnated fabric as rebar in Abaqus Standard. It seems that the rebar is only good in uniaxial tension load and it causes convergence problem in bending and compression loading. The fabric and rubber matrix has a compressive strength and that is critical to the model that I am analyzing. What would be a good approach to include compression on fabric rebar? The compressive strength of fabric matrix should be an order of magnitude lower than the tensile strength but I do not have a test data in compressive loading.
