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:

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.

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 20^th 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
