High-temperature extensometerDIC systemVideo extensometer
1600℃ High-Temperature 2D Extensometer Test

For the limited view through the small window of a high-temperature furnace, we recommended a 2D extensometer. By adjusting the device angle and optimizing the optical path, the 2D extensometer covers the key parts of the specimen within the limited view.

Deformation Test of Carbon Plate in High-Temperature Environment

Traditional contact measurement often interferes with the specimen surface in high-temperature tests, possibly affecting data accuracy. Haytham's monocular 3D video extensometer uses non-contact optical measurement, tracking carbon plate deformation optically to avoid physical-contact interference and ensure reliable test data.

300℃ Compression Test of 7mm Carbon Fiber Rebar

For high-performance carbon fiber rebar, any contact measurement may damage its surface and affect results. Haytham's monocular 3D high-temperature video extensometer monitors specimen deformation in real time via optical tracking without contact, preserving specimen integrity and providing accurate data for subsequent analysis.

Double-Cantilever Crack Propagation Analysis

In double-cantilever crack propagation analysis, Haytham's monocular 2D video extensometer analyzes crack growth behavior in real time and precisely through strain gradient, boundary recognition and residual gray-field modes. Strain gradient analysis identifies stress concentration regions of crack growth, boundary recognition tracks the crack path and width changes precisely, and residual gray-field analysis provides strain distribution around the crack, helping identify subtle changes in propagation.

High-Cycle Fatigue Test of Metal Materials

Haytham's monocular 2D video extensometer is equipped with a dedicated fatigue measurement module that, working with the controller and software, fits N small cycles of high-cycle fatigue testing into 1 large cycle. This effectively reduces the data acquired per fatigue cycle, while cross-cycle photo capture ensures the DIC system tracks the specimen's deformation throughout.

N-Value and R-Value Measurement of Sheet Metal

In the experiment, the sheet metal specimen was clamped in a tensile testing machine. Haytham's monocular 2D video extensometer monitored the specimen surface in real time and captured its deformation during tension. Based on method A of GB/T 5027-2016, the system precisely measured the plastic strain and computed the corresponding R-value. Since the system allows flexible selection of the plastic strain range, researchers can better control test conditions and ensure reliable results.

Reduction of area2D video extensometer
Measurement of Material Reduction of Area and Elongation After Fracture

Measuring reduction of area requires precisely measuring the specimen's cross-section dimensions before and after fracture, while measuring elongation after fracture requires the longitudinal elongation after breaking. Single-direction traditional measurement may miss transverse deformation, making the data less comprehensive; moreover, inevitable manual errors make precise measurement of these parameters even more challenging.
