- Final post from ECCM20
That’s it! – sadly ECCM is all over for another year.
What a tremendous conference – with so many fascinating and truly inspiring presentations given. All of the CerTest project group were able to meet old friends and to make many new connections.
Rafael Ruiz Iglesias (PhD Student, CerTest) said: “It’s been a great conference that composites researchers used for sharing ideas, network and having a good time! I would like to thanks first the Bristol Composites Institute and The CerTest project for this super opportunity and my supervisors Janice Barton, Ole Thybo Thomsen and Geir Olafsson for their big support through this event.”
The CerTest project team were joined at the conference by a wider circle of colleagues from the Bristol Composites Institute – see group photo below:
Looking forward to seeing everyone at ECCM21 in Nantes, France in 2024!
- CerTest update from ECCM
The ECCM20 Conference got off to a great start with an opening Reception at the Olympic museum overlooking Lake Geneva and the incredible mountainous scenery beyond.
Over the past two days members of the CerTest project team have already given some excellent presentations of their recent work. For some members this is the first in-person conference they have been able to attend, and all of the team are pleased to be able to network with others to share their research, discover synergies with the research of others, and forge new connections.
So far we have had the pleasure of hearing presentations from the following speakers:-
Monday, 27 June
Garden 6 / 17:15 – speaker: Roy BULLOCK (61961). Title: Ply Orientation Effects in Multidirectional Carbon/ Epoxy Open-Hole Specimens Subjected to Shear Loading.
Garden 6 / 18:45 – speaker: Neha CHANDARANA (62343). Title: Damage characterisation in open-hole composites using acoustic emission and finite element, validated by X-ray CT.
Tuesday 28 June
Garden 8 / 11:45 – speaker: Tobias LAUX (62344). Title: Hybrid testing for composite substructures.
Garden 5 / 14:30 – speaker: Aewis HII (62521). Title: Development of a Concurrent Multi-scale Analysis Framework using Shell Elements for the Progressive Failure Analysis of Composites.
This evening Prof. Janice Barton will present:
Garden 9 / 18:15 – speaker: Janice BARTON (62222). Title: A new test for validating models of lightning strike damage on CFRP laminates.
With many more to come over the next few days! Keep watching this space for a final update….
- CerTest – New Publication
We are happy to share our latest paper from the CerTest programme, which was recently published in Computer Methods in Applied Mechanics and Engineering.
In multiscale modelling of composites, computational homogenization allows us to link the behaviour of material on the finer length scale to a point on the structural scale. However, this process is associated with loss of spatial information on the larger scale. For example, a multiscale model would have information that a wrinkle exists somewhere in the material, but it will have no way of knowing its location. To do this, a second order computational homogenization technique which maintains spatial information has to be developed. This is the focus of our recent paper.
Our colleague Aewis Hii has done an impressive job putting this together. Thanks go to Bassam El Said and also to Stephen Hallett for his invaluable guidance. Here is an open access link to the article, we hope you find interesting:
- Prestigious Award for CerTest Research Challenge Leader
CerTest are delighted and extremely proud to announce that Prof. Janice Barton, (CerTest Research Challenge 3 Lead) was awarded the prestigious William M Murray Award for her lecture at the Society for Experimental Mechanics in 2020 and was finally able to be presented with the award in person at this year’s SEM conference in Pittsburgh (13-16 June 2022).
The award was in recognition of her pioneering contribution to the development of Thermoelastic Stress Analysis (TSA). It merits additional recognition as she is the first female recipient of this award.
The CerTest project team feel very lucky to have the benefit of Prof. Barton’s expertise in this area to help with the ground-breaking work being done on the project.
- CerTest goes to ECCM!
We are pleased to announce that a team of Academics, Researchers and PhD students from the CerTest project will be presenting their latest work at ECCM 20 (the 20th European Conference on Composite Materials) in Lausanne, Switzerland – 26-30 June 2022.
ECCM brings together participants from academia and industry who share an interest in Composite Materials and is the main European forum for Knowledge exchange on recent accomplishments and future trends in Composite materials.
This year’s conference is on the theme of “Composite meet Sustainability” and will highlight sustainability aspects (bio-based composite, energy efficiency in materials, production and use phases as well as end-of-life scenarios and recycling) in addition to the usual range of topics. Sustainability is very much in the core of CerTest, which aims to radically improve the efficiency of future composite aircraft, decrease of cost and time to market.
The CerTest team is proud to present the following:
The Principal Investigator, Ole Thomsen, Bristol Composites Institute, University of Bristol, will give an overview of the project:
Validation of Composite Aerostructures through Integrated Multi-Scale Modelling and High-Fidelity Substructure Testing Facilitated by Design of Experiments and Bayesian learning
