In the year 1000, dramatic cultural and political changes were underway in major regions of the world, including East and Central Asia. At Dunhuang, this was when the Library Cave (Cave 17) was sealed. Using the cave's contents as clues—some 40,000 objects, including manuscripts on spiritual, medical, philosophical and mundane matters, as well as paintings and textiles—Valerie Hansen, professor of history at Yale University, reconstructed the larger historical context of the Library Cave, the Thousand Buddha caves at Mogao, and city of Dunhuang, and the surrounding region.

![Understanding the Chemo-Mechanical Response of Oil Paint: An Integrated Numerical-Experimental Study
Full Lecture Title — Advancing Our Understanding of the Chemo-Mechanical Response of Oil
Paint(ings): an Integrated Numerical-Experimental Study
Presenter: Emanuela Bosco, Eindhoven University of Technology
Abstract:
Oil paintings age and degrade over time due to complex chemical and physical processes, affecting their appearance and longevity. This research aims to improve our understanding of the chemo-mechanical behavior of oil paintings through an integrated numerical-experimental approach. This presentation focuses on two main topics.
First, the formation and growth of metal soaps and their consequences on the mechanical response of oil paint are investigated through a coupled chemo-mechanical damage model [1]. The model is applied to analyze two case studies representative of typical metal soap-related degradation processes observed in oil paintings, revealing the influence of the growth of crystalline metal soap on the deformation of the paint surface and the consequent development of cracking and delamination patterns.
Second, to provide accurate input parameters for the model, a new experimental methodology is proposed to characterize the time-dependent mechanical and chemical properties of small-scale paint samples subjected to natural and artificial aging. This methodology combines micro-tensile testing [2] with real-time in-situ microscopic inspections based on digital image correlation. Chemical analyses of the paint samples finally provide insights into the relation between the chemical and mechanical responses.
