Description

Technical Field

[0001] The utility model relates to the technical field of ceramic material testing, in particular to a novel mechanical property testing device for ceramic materials. Background Art

[0002] Ceramic materials are a type of inorganic non-metallic materials, usually made from natural or synthetic compounds through forming and high-temperature sintering. They have the characteristics of high melting point, high hardness, high wear resistance, oxidation resistance, etc., so they are widely used as structural materials and tool materials. Ceramics also have some special properties that allow them to be used as functional materials. In the mechanical property testing of ceramic materials in related technologies, the testing device is often unable to monitor multiple points of the material at the same time, resulting in limited accuracy and efficiency of the test results. In addition, conventional testing methods usually lack the ability to monitor the deformation state of the material in real time, and cannot accurately control the pressure applied to the material, which further limits the accuracy of the test. In view of this, it is necessary to improve the current mechanical property testing device to solve the above problems;
