Digital Imagine Correlation (DIC) Method for Detecting Crack Development in Construction Materials Subject to Loading

Article Preview

Abstract:

The digital image correlation (DIC) technique is developed for identifying the crack development in brick wall and reinforced concrete beam. This method is tested on brick wall and reinforce concrete beam to evaluate the observation with various strain quantities and mesh sizes. The analysis results reveal that using the von Mises strain field will lead to fine precision of crack observation, and that clearer imagines can be obtained with smaller mesh sizes. This technique is capable of judging crack loading to predict crack occurrences.
