Application of 3D-DIC Method on Crack Forming Process of Concrete under Axial Compression


Article Preview

Applying 3D digital image correlation (3D-DIC) method to observe and investigate on crack forming process of C45 cylinder concrete under axial compression. The three-dimensional displacement and strain of the exterior surface of C45 concrete during the failure process are obtained. Furthermore, the location and shape of the crack are predicted with the generation, variation and aggregation of the maximum strain equipotential line on the concrete surface. The results show that the applying of 3D-DIC method can accurately obtain the concrete strain distribution data, predict the crack development trend and provide an important basis for further study on the mechanism of damage and fracture characteristics of concrete structure.
