A review on acoustic emission monitoring for damage detection in masonry structures

Abstract Acoustic emission monitoring is widely used for damage detection in materials research and site monitoring. Its use masonry structures however challenging due to the highly heterogenic nature of rapid signal attenuation. However, non-invasive high sensitivity technique also provide interesting opportunities, especially historical structures, locate damage, identify severity rate deterioration. Aim this paper an extensive literature review on application acoustic addressing specific challenges recent findings. AE-based methods assessment are discussed view approaches, wave propagation, source location crack development under static, fatigue creep loading. Site applications identifying propagation towers, buildings arch bridges. The concludes with future identified field.
