1. Background
The clothing industry is a major contributor to environmental pollution due to issues like dyes, microplastics, poor recycling, and the transportation impacts. In response to this, the European project UPWEARS, which involves 15 international partners, aims to produce prototypes of recyclable smart clothing with limited environmental impact.
One of the primary goal of UPWEARS is to develop digital framework for predicting sustainable European e-textile process outcome and product performance. This objective involves biosourced matrices and composites evaluation, finite element (FE) computations, topology optimisation, and additive manufacturing process simulation.
The PhD candidate will work in close collaboration with RISE.
FE-based structural analysis tool for textile & composites will be used to numerically simulate the multi-scale and multi-physics nature of the textiles and their composites.
These models will guide product design to achieve zero-defect products. Different constitutive models will be developed based on structural mechanics, transfer, thermal, and electric conductivity physics for fibre, yarn, textile, and composites to bridge the gap between the micro- and meso-scale and meso- and macro-scale performance modelling.
The complexity of the models may enforce some level of simplification where homogenised models will be considered as alternatives if computational efficiency would be challenged. This activity requires different sets of data to be collected from the multiscale characterisation tests planned from several partners such as SCION, CITEVE, UBS, SOLEIL, and UBFC.

Main missions
The main objectives are:
— Developing a numerical framework to reach zero-defect products according to
performance and durability criteria;
— Implementing multi-scale and multi-physics finite element computations to predict the
performance of e-textiles at different length scales;
— Gaining a deeper understanding of the variability effect of biosourced martials in the
behaviour of e-textiles and composites to maximise their performance;
— Optimising large-scale AM of recovered polymers from e-textiles using process
simulation with respect to energy consumption and part quality. Such optimisation will
involve sequential thermal-stress analyses;
— Participating in the consortium meetings, dissemination activities (scientific
publications, workshops, science or public fairs, first-hand demonstrator

Candidate background
We are looking for a highly motivated PhD candidate to work in an international
environment with partners in Sweden, Italy, Portugal, Belgium, UK and New Zeeland.
The candidate would preferably possess a strong background in numerical modelling
and/or engineering process simulation with an additional expertise in
material/mechanical science being advantageous.
In addition, knowledge of textiles, natural fibres and testing techniques dedicated to
mechanical, thermal, transfer analysis, as well as large instruments will be much
appreciated.
