High-speed cameras observe the deformation and instantaneous fracture of materials under force, and the entire process of crack propagation. The DIC (Digital Image Correlation) system analyzes the strain and force conditions, and calculates the material's elastic modulus, Poisson's ratio, R-value, and N-value parameters.
The DIC (Digital Image Correlation) system Obtain full-field strain data, stress distribution, and the evolution of cracks in key areas.
The DIC (Digital Image Correlation) system analyzes the vibration characteristics of components under internal and external vibration sources, measuring the natural frequency, damping ratio, and other information of the components.
The video extensometer records the sequential images of the experimental process in real time, measures both axial and transverse strains in real time, dynamically displays the axial and transverse displacements and strain curves of the component, and feeds the strain signals back to the testing machine in real time for closed-loop control.
