The Sardinian nuraghi network towards UNESCO

We are currently developing a digital twin designed to simulate the complex mechanical behaviour of a nuraghe, one of the widespread ancient structures that characterise the Sardinian landscape, with approximately 9,000 examples documented across the island. We are developing a detailed three-dimensional mechanical model, as simplified two-dimensional approaches are unable to capture the complexity of their geometry and, consequently, of the mechanical response.

The ultimate objective of this research initiative is the development of a reliable computational tool to assess the degree of safety of these sites of historical and structural relevance, that are subject to considerable public engagement. The project is coordinated by Emilio Turco and involves a multidisciplinary team comprising specialists in computational mechanics, Emilio Barchiesi, Mustafa Erden Yildizdag, and Chuong Anthony Tran, and archaeologists, Roberto Busonera and Ilaria Trivelloni. This collaboration seeks to integrate advanced computational modelling methodologies with specialised expertise in ancient construction techniques.

Following the conclusion of the current phase, a remote monitoring program will be implemented on a selected nuraghe prototype, enabling the refinement and calibration of the digital twin through data acquired directly from the physical structure.
