Abstract

Investigation of the deterioration of paintings requires not only the testing of archival samples but also the development and testing of model paintings which accurately represent naturally aged paintings. One aspect of this research is the characterisation of archival linings and the development of an ageing regime for new canvas. Assessments included uniaxial and biaxial tensile tests and the measurement of strain within stretched samples using electronic speckle pattern interferometry. The 19th-century linings tested have a mean strength of 15 that of new linen. Artificially aged linen (using 10 sulphuric acid) could be matched for archival strength and stiffness but further work is needed to achieve equivalent brittleness. Biaxial tests demonstrated that canvas on a stretcher would fail at loads lower than those expected from a simple consideration of the uniaxial strength, indicating the presence of strain concentrations approaching a factor of 10. This was confirmed using ESPI to map the strains.
