摘要

The meso-scale study can reflect the failure nature of fiber reinforced concrete, and the meso-level analysis can be used as the basis for the study of macro-mechanical response of concrete under load. With the aid of 3D-DIC digital image technology, the micro-cracking damage experiment of fiber reinforced concrete is carried out, and the evolution characteristics of strain field in the process of compression loading are analyzed. According to the full-field strain nephogram, the crack propagation and evolution of concrete can be judged. The deformation and failure mechanism of fiber reinforced concrete material is studied by using 3D-DIC observation system, which can be used for fiber coagulation. The study of soil meso-deformation and failure mechanism provides important reference.
