ANUBIS PROJECT

VASUKI RAJAKUMARAN successfully defended her PhD thesis on 19 December in Nantes, Congratulations Vasuki! 🎆 🥂 🎓 🎁 It is a great step and achievement for the ANR (Agence nationale de la recherche) ANUBIS PROJECT. Thank you to all the jury members and to the ANR (Agence nationale de la recherche) for funding the work.

Good news for ANUBIS PROJECT! The new paper of VASUKI RAJAKUMARAN is available online. The article is a numerical and experimental study dedicated to the mechanical behavior of modern and ancient flax yarns. The novelty of this study lies in linking mechanical behavior to fibre morphology and defects at multiple scales by utilizing X-ray microtomography to generate detailed 3D images of elementary flax fibres, enabling the creation of accurate finite element models for analysis. Numerical analysis highlighted higher stress concentrations at the kink-band region, particularly at pores in the kink-band region, which can initiate cracks and lead to rupture.

Enjoy your festive break for reading the last Camille Goudenhooft's paper; a fantastic Christmas' gift for our ANUBIS PROJECT! The main topic of the article is a comprehensive examination of ancient Egyptian flax fibres from four archaeological artefacts; we are proposing here a detailed characterisation of the fibre ultrastructure and micromechanical properties by combining nanoindentation (NI) and atomic force microscopy (AFM). This work highlights the complementary of these techniques for both heritage and materials science; it demonstrates on some samples, the remarkable cell wall stiffness, even after thousands of years, which is a key element for the bio-based composites sector, to better understand the degradation mechanisms of plant fibres. Thank you to all partners and co-authors; Eric BALNOIS, Olivier Arnould, Célia Caër, Camille Goudenhooft, Sylvie Durand, Alessia Melelli, Darshil Shah, johnny beaugrand, Anthony Magueresse, Anita Quiles, Alain BOURMAUD, Université Bretagne Sud, IRDL - UMR CNRS 6027/UBS/ENSTA-Bretagne/ENIB/UBO, Synchrotron SOLEIL, INRAE BIA, Institut français d'archéologie orientale - Ifao, ANR (Agence nationale de la recherche) More details here: https://lnkd.in/e9WPYAYB

Very productive period for ANUBIS PROJECT with the publication of the new paper of VASUKI RAJAKUMARAN in Industrial Crops and Products journal. The main objective of this work is to gain a comprehensive understanding of the damage mechanism in flax fiber bundles presenting a novel aspect due to the intricate structure of bundle fibers, which is more complex compared to elementary fibers. The study specifically explores flax fiber bundles under tensile loading and investigates the impact of kink-bands on their failure through a combined approach, utilizing both experimental and numerical methods. In the experimental part, X-ray microtomography in situ tensile testing is carried out, which reveals complex failure mechanisms. Furthermore, a 3D-Finite Elements (FE) model is implemented utilizing 3D reconstructed fiber and used for numerical tensile analysis. Our work highlights that the kink-band region acts as prominent failure site in fiber bundles with significant stress concentration at the kink-band region, mainly induced by local porosity. https://lnkd.in/eA-dG5Wd ANUBIS PROJECT, INRAE BIA, Université Bretagne Sud, IRDL - UMR CNRS 6027/UBS/ENSTA-Bretagne/ENIB/UBO, Institut français d'archéologie orientale - Ifao, Synchrotron SOLEIL, MISL Mines Paris PSL
