Publications

The AMOS project has been disseminated widely through a variety of means:

In November 2015, La Presse, a French magazine, included an excerpt about Fiona Zhao from McGill University. La Fabrication Additive à La Rescousse talks about Zhao’s research into additive manufacturing in the upcoming AMOS project, specifically how this technique could be used to improve aeronautic design and repair damaged aircraft parts.

In May 2016 the Nuclear AMRC reported on the AMOS project in the article New European-Canadian research to explore additive repair for aerospace. This press release was soon picked up by the HVM Catapult, magazines including Aerospace Manufacturing and Manufacturing and Engineering, and Rotherham Business News. The Canadian company Liburdi also reported on the collaboration and published Additive Manufacturing in the Aerospace Industry in the CWA Journal 20, April 2017.

Canadian students at McGill have submitted a number of theses regarding AMOS.

A presentation was given on the AMOS project during Centrale Nantes Open Day October 2017 and October 2018.

Furthermore, Xiaoyi Guan from McGill University in Montreal spent 10 days in France at the ECN campus in June for AMOS, looking at the additive machine which will be used to deposit Titanium in the project.

AMOS was presented at the poster session during CARIC'S 3rd National Research Forum, which showcases projects funded since CARIC's inception in 2014.

Udisien Woy from the University of Sheffield AMRC presented on Bulk Additive Manufacturing during the EASA Workshop in Additive Manufacturing, September 28th – 29th 2016, Cologne. Woy also gave an AMOS overview at the SAE AMS AM meeting hosted by Norsk Titanium, 23-26 April 2018, Norway.

The AMOS project featured in the conference proceedings for NordDesign 2018, Design in the Era of Digitalization, August 14-17, Linköping University. The paper, Integrating additive manufacturing and repair strategies of aeroengine components in the computational multi-disciplinary engineering design process, was highlighted during Session 5C on additive manufacturing (p.17 of programme). This paper was also highligted to industry during a training session at GKN Aerospace.

The AMOS project has been featured in Building expertise for additive repair, Nuclear AMRC News, No. 33 Q4 2018, p.9 and Additive repair for aerospace, Nuclear AMRC, Helping manufacturers win work in nuclear 2019 brochure, p.7.

In February 2019, the Nuclear AMRC news reported on how Udisien Woy discussed AMOS as part of the additive manufacturing showcase at the launch of Nuclear AMRC Midlands. Further details of this event can be seen on our website. ECN have also given an overview of AMOS on their open days.

The AMOS project featured in the conference proceedings for The 22nd International Conference on Engineering Design (ICED19), 5-8 August 2019, Delft, The Netherlands. The abstract for the paper, A lifecycle cost-driven system dynamics approach for considering additive re-manufacturing or repair in aero-engine component design, was featured in the Daily Book of Abstracts, Wednesday 7 August 2019, responsible design for our future, p.10.

Udisien Woy gave an overview of the AMOS project at TandemAEROdays 19-20, 27-30 May 2019 in Bucharest, and at the DREAM Summer School & Common Dissemination Booster, 3-7 June 2019, Italy. She also acted as AMOS session chair and gave an overview presentation at the 9th EASN International Conference on Innovation in Aviation & Space, 3-6 September 2019, Athens, Greece.

Findings from the AMOS project haved underpinned the following research:

- A State-Of-The-Art Review of Additive Manufacturing of Inconel Alloy 718, The University of Sheffield AMRC

- Thermo-Mechanical Modelling for Directed Energy Deposition, Digital Product Simulation

- Measuring Extreme Temperatures in Sand-Grain Sized Droplets of Liquid Titanium at Sub-ms Speeds, University of Ottawa

- A Quantitative Model of Competitive Grain Growth Behaviour in Direct Energy Deposition Fabricated Ti6AI4V, McGill University

- Directed Energy Deposition Topology Optimisation Study, Digital Product Simulation

The Marketing team at Nuclear AMRC created a video for the project - Amos: Chocolate Science & Aircraft Repair, December 2019. Dr Rahul Mandal, research associate at the University of Sheffield's Nuclear AMRC, talks about the Amos project to develop new additive techniques for aerospace repair – and why chocolate is a great tool for teaching young people about science and engineering. Dr Mandal won the ninth series of The Great British Bake Off in 2018 and posted the video on his Instagram profile, helping the exposure of the project. To date, the video has been viewed by approximately 20,000 people.

The University of Sheffield AMRC have participated in a number of STEM events for 11-15 year olds, promoting engineering and explaining additive manufacturing and its impact on resource efficiency.

The University of Sheffield has an ongoing commitment to the SAE ‘Repair’ Committee through working group participation.
