Abstract

This investigation determined the smallest strain accurately measurable by a state-of-the-art digital image correlation (DIC) – based tool used in structural health monitoring, in a specimen subjected to out-of-plane movement, building upon a study that concluded that out-of-plane specimen movement results in noise in DIC-based strain measurements. This study was motivated by initially undetected damage at low strains in connections of a real-world bridge, whose detection would have prevented its propagation, resulting in lower repair costs. The smallest strains accurately measurable using the state-of-the-art DIC tool, over a range of specimen out-of-plane displacement amplitudes, were determined.
