Preparation of rock splitting sample

DIC technique is used to study the full-field deformation and localized failure characteristics of rock in the process of Brazilian splitting failure

High-speed cameras capture images of the rock fracturing process

UCD208A101-3BHE020018R0101 DIC software analysis found that the maximum principal strain in X/Y direction and the crack change trend were obvious during the rock material splitting process. The maximum strain region was analyzed by chromatogram, and the crack evolution and specific values were analyzed.

DIC test application of uniaxial compression of rock

The maximum compressive stress that the rock can bear before failure under uniaxial compression load is called the uniaxial compressive strength of the rock. XTDIC three-dimensional full-field strain measurement system and high-speed camera are adopted to carry out full-field strain observation during the test process with a non-contact acquisition frequency of 5000 frames. The macroscopic mechanical parameters, spatial strain field evolution and failure modes of rock samples are compared and analyzed.
