[0029] Preferably, both the first sample fixture and the second sample fixture have built-in mechanical sensors for detecting the stress conditions of the material during the test.

[0030] The working principle and workflow of the utility model are:

[0031] (1) The pneumatic part 13 of the first sample clamp acts on the lower sandwich layer 11 of the first sample clamp, so that the upper sandwich layer 10 of the first sample clamp cooperates with the lower sandwich layer 11 of the first sample clamp to pneumatically clamp one end of the sample. Similarly, the pneumatic part 19 of the second sample clamp acts on the lower sandwich layer 18 of the second sample clamp, so that the upper sandwich layer 16 of the second sample clamp cooperates with the lower sandwich layer 18 of the second sample clamp to pneumatically clamp the other end of the sample, thereby clamping the sample to be tested;

[0032] After the camera moving frame 1 slides vertically up and down along the camera support rail 2 to a suitable height, the moving frame fixing screw 3 is tightened to fix the position of the camera moving frame 1, and the vertical height of the camera 8 is adjusted; the camera fixture connecting shaft 4 slides horizontally in the camera moving frame 1, thereby adjusting the horizontal position of the camera 8; the camera 8 rotates in the camera fixture 6, thereby adjusting the shooting angle of the camera 8;

[0033] (2) Start the test:

[0034] Working condition 1: The first motor 23 and the second motor 32 drive the first roller screw 25 and the second roller screw 30 to rotate respectively. The rotation of the first roller screw 25 and the second roller screw 30 drives the first screw nut 26 and the second screw nut 29 to move in opposite directions respectively, thereby driving the first sample fixture fixing plate 14 and the second sample fixture fixing plate 20 to move in opposite directions, and observing the fracture dynamics and mechanism of the entire sample;

[0035] Working condition 2: the second motor 32 is not started, and the first motor 23 is started; the first motor 23 drives the first roller screw 25 to rotate, and the rotation of the first roller screw 25 drives the first screw nut 26 to move, and then drives the first sample fixture fixing plate 14 to move, at this time the second sample fixture fixing plate 20 does not move, and the fracture dynamics and mechanism of the sample in the left half are observed;

[0036] Working condition three: the first motor 23 is not started and the second motor 32 is started; the second motor 32 drives the second roller screw 30 to rotate, and the rotation of the second roller screw 30 drives the second screw nut 29 to move, and then drives the second sample fixture fixing plate 20 to move. At this time, the first sample fixture fixing plate 14 does not move, and the fracture dynamics and mechanism of the sample in the right half are observed.

[0037] The clamped sample will be stretched and deformed until it breaks under the action of external force. During this process, the camera 8 captures the sample morphology changes and fracture process at a speed of 10 to 50 ms / time. Combined with the data measured by the built-in mechanical sensors of the first sample clamp and the second sample clamp (such as the force required before, during, and after the sample breaks), the fracture strength and elongation of the material are obtained, the fracture morphology of the material is recorded, and the tensile morphology and fracture mechanism of the sample under different external forces during the whole process are analyzed.

[0038] Anything not described in the present invention is applicable to the prior art.
