Camera
Instrument for fatigue resistance tests in bending and in tension at controlled temperature (-40 ÷ + 200°C) with automatic inspection of the specimens through video cameras
Standards the instrument complies with:
ASTM D813; ASTM D430-B; ISO 132; ISO 6943; JIS K_6260;

Gibitre’s temperature-controlled fatigue tester merges automated image capture with AI to identify crack initiation in real time. As a precise measurement tool among your lab’s tools, it rigorously documents damage evolution during bending on diverse materials. The integrated climate chamber operates from -40 to +200 °C with on-board refrigeration, while counter-moving specimen holders minimize noise and vibration. A 12-position rack enables simultaneous tests with user-set frequency (0–300 rpm), stroke (0–60 mm), clamp distance (up to 100 mm), and cycles (up to 10,000,000). Six high-resolution cameras, strain-synchronized, film the bending zone of all specimens without pausing the run. The 15'' touch software logs images at chosen intervals, applies AI crack detection, and auto-generates a cycle-indexed video; data export via USB or network. CE marked; suitable for fatigue and bending tests in accordance with ISO 132, ISO 6943, ASTM D430-B, ASTM D813.
An instrument with Unique Features
This revolutionary Flexometer De Mattia, equipped with Climatic Camera for performing temperature-controlled tests and 6 Video Cameras for capturing and analyzing images of the 12 specimens produces as an automatic test result a Video of the progressive degradation of the specimen during the entire test cycle.
The instrument, which captures images without interrupting operation, dramatically reduces the testing time by eliminating all the interruptions and manual tasks that are normally required to evaluate the status of specimens.
The video and images produced make it possible to objectively document the results of the testing, allowing analyzing crack evolution in extreme detail.
Test Setups
The instrument allows all test parameters to be set at the beginning of the test:
Oscillation frequency (0 ÷ 300 rpm)
Stroke (0 ÷ 60 mm)
Test temperature (-40 ÷ +200°C)
Total number of cycles (max 10,000,000)
Test modes (Fatigue, Crack Growth)
Illumination of the specimens
Identification of the 12 specimens
Frequency of image acquisition
Performing the test
To perform the test, simply insert the 12 specimens into the instrument, and press start.
The instrument automatically adjusts the temperature and following thermal conditioning begins the test cycle by recording images of each specimen without stopping the oscillation until the total number of cycles set is reached.
The Artificial Intelligence algorithm analyzes all images to determine the presence of cracks (Fatigue Test) or crack size (Crack Growth Test)
At the end of the test, all images for each specimen are automatically edited into a video that includes useful information (Number of Cycles, Crack Presence/Size, Temperature). Videos of the 12 specimens are downloadable via USB or LAN port.
Temperature Range
The sample holding system is located in a Environmental chamber which permits to set the temperature between -40°C and 200 °C.
Image acquisition system
The instrument is equipped with 6 BW video cameras with a resolution of 600x450 pixels that allow you to simultaneously acquire the images of all 12 mounted specimens (each video camera acquires the image of 2 specimens).
A LED lighting device has been developed which guarantees the correct illumination of the specimens and, in combination with the software setting of the exposure of the cameras, allows to obtain optimal images for specimens of various colors.
Image acquisition and lighting are synchronized with the movement of the specimen to always acquire the image in the same position (settable) without interrupting the operation of the instrument
The frequencies of acquisition and saving of the images before the crack is identified and after its identification can be set by the user based on the characteristics of the product to be tested (minimum frequency per sample 20 seconds)
Control device
The complete control of the instrument is carried out through the powerful software installed in the PC inside the machine and through the 15 '' touch-screen control panel.
The software allows you to:
- Set the frequency, the temperature and the number of cycles to be carried out
- Identify the 12 specimens
- Record the images of each of the 12 samples with set frequency
- Analyze images with Artificial Intelligence algorithm for automatic detection of the crack start
- Perform a slide-show of the images recorded for each sample
- Download the images via USB port to an external support
Management of Sample Images
The images related to each specimen are saved in the internal memory of the device (up to 10,000 images can be stored)
The software allows you to view all the images related to each specimen in sequence
The name with which each image is saved includes the position, the identification, the number of cycles performed at the time of setting, the presence of crack.
Artificial Intelligence Algorithm
The analysis algorithm analyzes all images to identify the presence of cracks.
The algorithm was educated in acquiring images of specimens with different colors and polymers.
When the algorithm identifies the presence of a crack, the software records the number of cycles at which the crack identification occurred and automatically changes the image saving rate based on the settings.
Automatic generation od the movie for each sample
The management of thousands of images for each sample requires time and memory for storage.
The software of the instrument automatically produces a movie for each sample using the images stored. The movie shows the evolution of the sample and the corresponding number of cycles. The movies can be downloaded to USB of using network connection.
Sample holders
The sample holder permits to test 12 samples simultaneously.
The exclusive movement system with both sample holders moving in opposite directions ensures extremely low levels of noise and vibrations.
Instrument Regulation
According to test specification, the instrument can be easily adjusted by setting
• Test frequency (60 to 300 rpm)
• Test stroke (0 to 60 mm)
• The distance of the grips (up to 100 mm)
• The number of cycles before automatic stop can be set (up to 1.000.000)
Cooling system
The instrument produced by Gibitre uses a Refrigeration Unit to reduce the temperature.
The use of the refrigeration unit, compared to cooling by liquid nitrogen, allows to:
• control the test temperature perfectly, avoiding oscillations that may alter the results.
• Carry out long-term tests without risking to end the liquid nitrogen supply before finishing the test
• Eliminate the hazards related with manipulation of nitrogen
