This study illustrates how a series of scientific observations and instrumental analyses can be used to construct a numerical simulation that allows a deeper understanding of the physical structure and behaviour of the object itself, namely to construct a hygro-mechanical predictive model (a “Digital-Twin”) of Leonardo da Vinci's Mona Lisa panel. Based on specific request from the Louvre Museum, a group of experts with different and complementary skills cooperated and are still cooperating to construct a complete set of experimental observation and non-invasive tests; so, the integration of the collected data made the construction possible of the panel’s Digital-Twin. This paper also specifically examines how the Digital-Twin can be used to compare two framing conditions of the panel; although the two experimental configurations are not inherently comparable, the comparison is made possible by the introduction of a technique of projection of the fields obtained as results of the two analyses, named the Projected Model Comparison (PMC), which has been developed specifically for this research. %G English %2 https://hal.science/hal-03053193/document %2 https://hal.science/hal-03053193/file/20200216HerieTech2020_draft_Riparbelli.pdf %L hal-03053193 %U https://hal.science/hal-03053193 %~ PRES_CLERMONT %~ CNRS %~ UNIV-BPCLERMONT %~ UNIV-POITIERS %~ ENSMA %~ LMGC %~ INSTITUT_PASCAL %~ PIAF %~ MIPS %~ UNIV-MONTPELLIER %~ PPRIME %~ C2RMF %~ INRAE %~ TEST-HALCNRS %~ UM-2015-2021 %~ TEST3-HALCNRS %~ RESEAU-EAU %~ DPT_ECODIV %~ ISAE-ENSMA
