Concrete Stress-Strain Characterization by Digital Image Correlation

On the Use of Acoustic Emission and Digital Image Correlation for Welded Joints Damage Characterization

A series of tests have been conducted to investigate fatigue damage characterization in corroded welded steel plates using structural health monitoring (SHM) techniques. Acoustic Emission (AE) is a non-destructive testing (NDT) technique with potential applications for locating and monitoring fatigue cracks in service. In the present work, AE is implemented to characterize damage during crack e...

Processing Digital Image for Measurement of Crack Dimensions in Concrete

The elements of the concrete structure are most frequently affected by cracking. Crack detection is essential to ensure safety and performance during its service life. Cracks do not have a regular shape, in order to achieve the exact dimensions of the crack; the general mathematical formulae are by no means applicable. The authors have proposed a new method which aims to measure the crack dimen...

Digital Image Correlation and the Contributions of Stress-Strain Measurements towards Failure Analysis

Failure mechanisms contributed by stress or material fatigue have been witnessed in several industrial as well as at R&D applications in various forms. Metallurgical studies for failure analysis have ensured the contributions of residual stress in several cases. The most important and common consideration in all these cases has been the material. Definitely, there may be other contributing fact...

Crack Monitoring and Strain Measurement in Asphalt Mixture by Digital Image Correlation

A full field method for the description of in-plane strain fields is applied for improving Asphalt Mixture cracking behaviour insights. A Digital Image Correlation (DIC) system based on the Least Square Matching technique is used to compute strains and depict crack path in the process from microcrack initiation to failure. A Brazilian test was performed using hole-notched specimens. The test ge...
