Problems solved by technology
For detecting the shear strength of the material, the existing technology is to use a circular piercer to compress and shear, apply a shear load to the sample, and cause the sample to produce shear deformation or destruction, so as to measure the shear strength of the material. However, the perforation method is not suitable for dynamic cutting detection of samples.

Description
technical field [0001] The invention relates to a detection device, in particular to a dynamic cutting detection device and detection method Background technique [0002] The mechanical properties of a material refer to the mechanical characteristics of the material when it is subjected to various external loads (tension, compression, bending, torsion, impact, alternating stress, etc.) under different environments (temperature, medium, humidity). Including material strength, hardness, rigidity, plasticity and toughness. These mechanical properties need to be measured on a material testing machine with standard samples according to the specified testing methods and procedures, which is the main basis for determining various engineering design parameters. [0003] The material testing machine is a mechanical force testing machine used for static load, tension, compression, bending, shearing, tearing, peeling and other mechanical properties testing of various materials. It is ...
