The large deformation video extensometer is a non-contact, high-precision real-time measurement system for significant deformations.
It utilizes a standalone digital camera and real-time image processing algorithms to capture images of the specimen during the testing process. By analyzing changes in image features, it can dynamically and in real-time measure data such as strain and displacement, accommodating tests with deformations of 1000% or more. It is particularly suitable for testing materials like rubber and films and supports signal communication with the testing machine to measure various mechanical performance parameters, including stress-strain curves, and can be used for a variety of large deformation mechanical tests.
1,Non-contact measurement: Avoids additional influences on measurement from contact methods such as strain gauges and clip-on extensometers.
2,Full process tracking: No need to stop the machine during the entire process; the testing machine will not be damaged even if the specimen breaks, allowing for full process tracking.
3,Diverse scenarios: In addition to general scenarios, it can also adapt to special experiments such as large deformations, small deformations, and high/low temperatures.
4,Broad material adaptability: There are virtually no restrictions on materials; it can be used for testing specimens of different sizes and materials.
5,Sub-pixel measurement accuracy: Based on image processing correlation methods, the calculation accuracy reaches the sub-pixel level.
6,Large strain range: The measurable strain range is from 0.002% to over 1000%, far exceeding traditional methods.
7,Customizable gauge length: The gauge length can be customized, with any setting within hundreds of millimeters.
8,Easy marking: No need to paste marks; marks can be made quickly and simply, ensuring that marks do not fall off during large deformations.
9,Multi-directional simultaneous measurement: Can calculate longitudinal and transverse strains simultaneously.
10,Multi-point pair measurement: Can measure strain at multiple points, suitable for multi-specimen testing and multi-stage testing.
