Digital Image Correlation (DIC) enables direct measurement of the mechanical behavior of rock mass surfaces. By capturing displacement and strain characteristics on rock and soil surfaces, DIC can detect failure forms, failure locations, affected areas, and the development trends of rock masses under external forces.

DIC provides a reliable scientific research tool for material and structural safety assessment in engineering construction. It is widely used in applications such as rock and soil triaxial compression tests, geotechnical splitting tests, slope vibration tests, 3D printed concrete material and structure tests, recycled concrete structure tests, and construction engineering material tests.

DIC technology is essential for analyzing both the full-field and localized deformation of rocks, including the evolution process of shear zones.
