Abstract

The aim of CerTest is to develop the building blocks that enable lighter, safer and more cost efficient composite aerostructures. The research will result in a new approach for integrated high‐fidelity structural testing and multi‐scale statistical modelling through Design of Experiments (DoE) and Bayesian Learning. The underlying assumption is that it is possible to develop a more cost/performance optimised philosophy, by reducing the level of physical testing, especially in the bottom/top levels of the test pyramid. Instead, structural behaviour is accounted for in a new culture of virtual design and validation that promotes a change towards virtual testing, enabling reduction of empiricism, mass savings, expansion of the design and performance envelopes, and reduction of design costs and associated development time.

Bibliographical note

Funding Information:
Evidence has emerged, that current test, simulation and certification approaches, as outlined by the generally adopted “building block” approach [1], inhibit the efficient exploitation and optimisation of advanced composite aerostructures. The Programme Grant “Certification for Design: Reshaping the Testing Pyramid” or “CerTest” funded by the UK Engineering and Physical Sciences Research Council [2],[3] seeks to break this impasse. The academic partners are the Universities of Bristol, Bath, Exeter and Southampton. Industrial partners include Rolls Royce, Airbus, GKN Aerospace and BAE Systems. CerTest is also supported by the Alan Turing Institute and The National Composites Institute (NCC), Bristol, UK.

Funding Information:
The research is supported by the EPSRC Programme Grant ‘Certification for Design – Reshaping the Testing Pyramid’ (CerTest, EP/S017038/1 [2]). The support received is gratefully acknowledged.
