Rock Core Compression Strain Test

In rock core compression strain testing, DIC technology (digital image correlation technology) has become an important non-contact measurement method. Through the application of the Haytham high-speed visual strain gauge, DIC technology can monitor in real time the full-field strain of rock cores during compression. Compared with traditional point-wise measurement methods, DIC technology provides more accurate and comprehensive strain data.

During the compression of rock cores, DIC technology the minute displacements and deformation on the rock core surface are captured to help researchers analyze the mechanical properties of the material. For example, when the rock core is subjected to external forces, DIC technology can identify stress concentration regions, thereby effectively predicting possible crack propagation and the ultimate failure point of the core.

In addition, DIC technology is applied not only in geological research but also widely in industries such as petroleum exploration and mineral resource extraction. In these scenarios, DIC technology provides high-precision full-field strain data to help engineers optimize construction plans, reduce risks, and improve operational efficiency.
