3D Microwave Imaging Technology For Damage Detection of Concrete Structures
Various nondestructive evaluation (NDE) techniques have been studied to locate steel rebars or dowel, and to detect invisible damage such as voids and cracks inside concrete and debonding between rebars and concrete caused by corrosions and earthquakes. In this study, the authors developed 3-dimensional (3D) electromagnetic (EM) imaging technology to detect such damage and to identify exact loc...
متن کاملMicrowave Imaging Using SAR
Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...
متن کاملCharacterisation of Cracks in Concrete by Shearwave Reflection Technique
The characterisation of cracks has stepped forward from a laborious investigation of small areas or lengths of a crack found by visual inspection to a technique which even can make use of automated scanning methods and which produces images of cracked and deteriorated areas in the volume of the structure under investigation. This progress is based on the application of novel transducers and nov...
متن کاملCracks Analysis in Zavin Concrete Dam Using Fracture Mechanics Approach
Most of the existing concrete dams are subjected to cracking. These cracks are caused by various factors such as construction practices, curing, loads and volume change of mass concrete which reduce the efficiency, failure or instability of concrete dams. Using fracture mechanics as a new method to estimate stability and durability of concrete dams is recommended in scientific publications in w...
