How to test video extensometer with universal testing machine? By applying a controlled force or stress, the universal testing machine carries out tensile, compressive, bending, torsional and shear tests on various materials to evaluate the mechanical properties and durability of materials. The video extensometer can be connected with the universal testing machine to record the deformation and destruction process of the material in the test in the form of video.

On-line use can intuitively understand the deformation behavior of materials under different loads, and accurately evaluate the performance and reliability of materials. Next, the application cases of XTDIC-VG video extensometer combined with universal testing machine for material testing are introduced.

The XTDIC-VG video extender uses a non-contact measurement method to accurately measure the elongation of thin film, foil, rubber, wire and other low-rigidity materials through the full dynamic synchronization of the measuring head of the industrial camera and the test software.

 

3. GF1-10TVD-102 XTDIC-VG video extensometer test process (with universal testing machine) :

1. Preparation: Ensure the normal operation and calibration of the testing machine and video extensometer.

2. Connection: Connect the video extensometer device to the testing machine and configure compatibility.

3, set parameters: set the loading rate, test mode and data acquisition parameters in the control software of the testing machine.

4, start the test: clamp the sample, start the testing machine and apply the load.

5. Data recording: the video extensometer records deformation and damage behavior during the test.

XTDIC-VG video extension meter can communicate with the testing machine equipment, and the measured value is transmitted from the video extension meter to the testing machine through the digital or analog interface, which meets the 0.2 accuracy requirements of the JJG 762-2007 extension meter metrological verification regulation. Supports the measurement of point, point pair and full-field strain data in 2D and 3D measurement scenarios, with a field of view up to 150mm.

The video extensometer is fitted with the environment box

The XTDIC-VG video extender provides reliable measurement results when tested in high temperature environments and with a high temperature test chamber. The window of the high temperature test chamber is made of optical glass, and the XTDIC-VG video extender can observe small Windows, capture clear images under high temperature environment, output stress-strain curve, elastic modulus, Poisson ratio and other parameters.

Continuous measurement of the loading process of rod materials at different temperatures:

a. Continue to record load and displacement data until the sample breaks.

b.GF1-10TVD-102  The video extender continuously captures and records the tag position until the break occurs.

Data analysis:

a. Draw the tensile curve according to the recorded load and displacement data

b. The output includes stress-strain curve and load-displacement curve.

Elastic modulus test of carbon fiber material

Through the XTDIC-VG video extensometer, the deformation value can be transmitted to the test machine in real time, and the stress-strain curve can be obtained by the test machine, and finally the elastic modulus, fracture elongation and other parameters can be calculated.

XTDIC-VG video extender has obvious advantages in the test of small-size material specimens, and can be used in the range from mm to μm. It can capture the whole process of stretching to breaking, avoiding the impact of clamping on the soft material; In situ fatigue test for small sample high and low temperature test.
