This technical study examines the mechanical behavior of canvas paintings, focusing on the physical stresses and environmental factors that contribute to their deterioration. Authored by Alain Roche, the book provides a scientific analysis of how paint layers and supports respond to changes in temperature, humidity, and handling. It serves as a critical resource for conservators and art historians, offering insights into preventive conservation strategies and the long-term preservation of painted artworks. Published by CNRS Editions, it bridges the gap between materials science and art conservation.
