XTVG is a leading professional software for strain measurement. Designed for ease of deployment and reliability, XTVG is compatible with a wide range of testing methods and testing machines. Based on digital image correlation (DIC), XTVG uses real-time continuous image acquisition to calculate various data types, including target coordinates, displacement, and strain, and outputs measurement results and generates reports. It also combines testing machine data (load values) to analyze and calculate material properties.
