On the analysis of canvas wrinkling via isogeometric stereocorrelation
Résumé
Wrinkling is to be avoided in the restoration of works on canvas. In the worst cases, it may lead to paint cracking. Visual rendering of the paint may also change because of such mechanism. It is proposed to measure wrinkling under various conditions of contrast and loading via isogeometric stereocorrelation. This method allows low contrasted paints to be analyzed in addition to very large deformations that occur in punch tests on canvas.
