[3A4] NDE measurement requirements for real-time updating of digital twins

Digital twins are becoming increasingly important across engineering sectors, as an integral part of Industry 4.0. This digital representation of a physical structure or system can follow the real-life counterpart throughout its life, from development through to in-service use. During development, a digital twin enables virtual prototype testing, by replacing physical tests that can be costly and impractical. In service, a digital twin can be used to optimise operations and maintenance schedules.
So that these are true digital ‘twins’ of the physical asset, data must be exchanged between the physical object and its digital twin in real time. Measurement data collected through non-destructive evaluation (NDE) techniques are therefore essential to inform a digital twin of the condition of the physical object. Currently, requirements for data collection and approaches for data exchange are not well defined.
A series of semi-structured interviews with industry experts has been carried out to survey the current practices in the application of digital twins and the workflows in place for the use of NDE techniques across engineering sectors. Results from this survey will inform a roadmap for the development of data collection approaches, digital twin design and data exchange pathways between the physical and virtual worlds.
