Title: Damage Behavior of Yarn Embedded in Concrete Using Acoustic Emission Analysis
Author(s): Bong-Gu Kang, Joachim Hannawald, and Wolfgang Brameshuber
Publication: Materials Journal
Appears on pages(s): 95-101
Keywords: acoustic emission analysis; damage; load-bearing behavior; textile-reinforced concrete
Abstract:To analyze the damage and failure mechanisms of a multifilament yarn embedded in concrete during a pullout test, an acoustic emission analysis was carried out for the identification and localization of filament ruptures. The different damage mechanisms (filament rupture, filament debonding, and concrete microcracking) causing acoustic emission were first characterized for separation. Tests were carried out to generate isolated signals, which were studied using signal and frequency analysis. A high localization accuracy of the filament ruptures in the yarn pullout test could be achieved, and the damage progress of the yarn during the pullout test could be analyzed in detail.
