Abstract

Virtual Fatigue Testing (VFT) can be defined as the high-accuracy simulation of the behaviour of high-fidelity ‘digital twins’ representing physical test articles in their test environment. The final aim of virtual fatigue testing is to provide an alternative to physical fatigue tests as the main source of certification evidence, as requested today by most civil and military airworthiness regulations, thus enabling the so-called ‘certification by analysis’.

This paper presents the work developed by Airbus towards the practical implementation of VFT capabilities for the assessment of military aircraft. A key factor for the eventual success of VFT is the ability to select and incorporate the latest simulation techniques in this field while keeping a reasonable computational cost. The selected methods need to cover all the phases of a standard fatigue test: crack initiation, crack growth and residual strength. The scope of VFT will include also the systematic evaluation of the statistical uncertainties replacing the traditional use of scatter factors.

Finally, the overall quality of VFT as certification evidence is addressed, because the fulfilment of the eventual requirements for the acceptance of virtual tests by the Airworthiness Authorities is an integral part of the development. Therefore, the criteria for verification, validation and final certification being created for this purpose are also discussed.
