Description/Abstract

Digital image correlation (DIC) is used to monitor strain in a representative textile
material and an historic tapestry. The validity of a ‘map function’ that allows 3D DIC displacement
measurements to be obtained when the reference data are collected with a camera set-up different
from that of the deformed data is assessed. An experiment was devised to study the effects of DIC
processing parameters (interrogation cell size and overlap) on strain measurements, and to investigate
if the textile contains adequate contrast for DIC to operate. The study shows that the textile’s
weave pattern can be used as the device for correlation. Long-term tests for monitoring creep strain
using DIC both in the laboratory and in situ are presented. The results show good correspondence
between strain changes in the tapestry and relative humidity.
