Cultural heritage paintings change and degrade with time. This is due to complex physical and chemical processes that lead to changes in the visual appearance and affect the integrity and longevity of the artworks. This research aims at gaining an in-depth insight into the multi-physics behaviour of historical oil paintings due to chemically- and moisture-induced damage mechanisms. This presentation will cover three main topics: i) the development of a chemo-mechanical damage model that describes the chemical process of metal soap formation and growth inside an oil painting [1]; ii) the development of an analytical model to extract the material properties of embedded (paint) materials from nano-indentation tests [2], and iii) the development a model to predict crack channelling and delamination mechanisms in paintings due to indoor climate fluctuations [3].
