XTDIC three-dimensional full-field strain measurement system adopts non-contact strain measurement method, which is based on digital image correlation technology (DIC) technology, suitable for material strain and structural deformation, crack, fracture and damage analysis and testing. DIC three-dimensional strain measurement system can be used for three-dimensional vibration and deformation measurement, measuring the three axis displacement of the object surface. The strain division of the material surface can be calculated automatically from the obtained results.

330101-20-45-10-02-01 In traditional rock mechanics tests, strain gauges are used for strain measurement. The strain gauge tends to measure the strain in a fixed direction and cannot achieve full-field measurement. The strain gauge can not accurately measure the maximum strain area because the rock deformation or fracture occurs in a large range.

330101-20-45-10-02-01 XTDIC three-dimensional full-field strain measurement system can obtain images of rock failure process, determine rock fracture properties, and analyze the displacement field and strain field of rock in the process of rock splitting failure in Brazil.

Brazilian rock splitting DIC test application

In the rock splitting test in Brazil, XTDIC three-dimensional full-field strain measurement system was combined with high-speed cameras to capture images of the rock failure process at high speed, and combined with DIC software to analyze the quantitative full-field strain diagram (tensile, compression and shear) generated under load to show the rock failure process and strain evolution process.
