Problems solved by technology
[0006] In engineering operations, some material fracture accidents usually cause huge property losses and seriously affect personal safety. Therefore, a series of fracture criteria that are convenient for engineering applications are urgently needed. In the process of theoretical research on fracture prediction, a reliable and practical test fixture is urgently needed
[0007] Existing fracture test fixtures can only be loaded with a single type of crack, or can only be adjusted at several fixed angles, which greatly limits the range of test data acquisition and cannot meet the test requirements of fracture theory research.

Embodiment Construction
[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0027] Such as Figure 1-6 As shown, a three-dimensional composite fracture test fixture includes a pair of C-shaped arc plates 1 that are arranged up and down oppositely and coplanar. Arc chute 11, the central angle of the arc chute 11 is 90 °, and the position corresponding to the arc chute 11 on the C-shaped arc plate 1 is provided with a 4-axis shaft reflecting the mechanical load of the experiment and the sample. The angle scale I12 of the angle between them. On the inner wall of the C-shaped arc plate 1 , a chassis 2 is relatively fixed up and down. Preferably, the chassis 2 is welded on the inner wall of the C-shaped arc plate 1 .
[0028] The chassis 2 is rotatably provided with a three-jaw chuck 3 that ca...

The invention relates to a three-dimensional composite fracture test clamp, which comprises a pair of C-shaped arc plates in vertically opposite arrangement. A circular arc slide groove for fixing theC-shaped arc plate onto a test machine through positioning screw bolts is formed in the C-shaped arc plate; base plates which are respectively and vertically fixed are also arranged on the inner wallof the C-shaped arc plate; a three-jaw chuck capable of fixing a test specimen is rotatablely arranged on the base plate; the test specimen is in a cylinder shape with fracture veins. The three-dimensional composite fracture test clamp has the beneficial effects that the problem of angle jumping regulation in the fracture test can be solved; the test data obtaining range is expanded; a reliable and practical test clamp is provided for really reflecting the composite type fracture rule.
