The stress comprises the process of stretching or compressing a small sample, and is completed by adopting a thermal simulation tester. The patent with application number of CN200520043903.4 discloses a clamp for a tension test of an extremely thin plate belt, which is characterized by comprising two bolts and nuts, wherein the bolts consist of nuts and screws, the screws of a first bolt are screwed with the two nuts, the screws of a second bolt are provided with inner holes, the inner holes are provided with inner threads, the second screw is sleeved on the first screw, the top of the second screw and the nuts screwed on the first screw clamp a sample, and the pin holes of a pull rod of a stretcher are sleeved on the first screw and the second screw. From the selected plate and strip sample, the two ends of the plate and strip sample need to be symmetrically drilled, the plate and strip sample is sleeved into the holes through the screw rods, and then the sample is subjected to tensile deformation, however, when the plate and strip sample is high in strength, the part of the sample, which is in direct contact with the screw rods, is subjected to great stress and is easy to tear, so that the test is failed, and the asymmetry of the drilled holes on the plate and strip sample also easily causes the deviation of the test result. Therefore, in order to reliably perform the test, there is also a need to provide a better clamping device for the plate and strip sample and a design method for the same.
