The health monitoring prescription by novel method

Abstract

This paper presents, knowledge of the way in which cracks are propagated within the material is a key aspects of understanding. The paper mainly focused on full-field measurement method such as digital image correlation (DIC) is increasingly used in the field of experimental mechanics for non-destructive evaluation system. The study is based on displacement error assessment from synthetic speckle images. The use of an image analysis procedure to capture the crack initiation and propagation process is described, which utilizes digital images of the concrete structure while undergoing the cracking process. It introduce concepts from the very basics and lead to advanced modeling (analytical or numerical), practical aspects (including software or hardware issues). The formed cracks are visible at relatively small crack openings, allowing a thorough investigation and analysis of the cracking process in concrete structure. The resulting displacement information reveals the average motion present from the center of each of the small sub images used in the analysis, relative to the original position. It uses image processing to go from several images of material, and to then calculate the deformation at any point in the field, and to then find crack propagation and strain values. The results obtained with this method have shown that it is possible to monitor relatively small displacements on the specimen surface independently of the scale of the representative area of interest. These results show a great application potential of the DIC technique for various situations such as inspecting shrinkage-induced cracks in fresh concrete, masonry and reinforced concrete structures, and safety of bridges.
