Description

technical field [0001] The invention relates to the technical field of detection, in particular to a high-precision tensile, compression and bending performance testing and analysis equipment and method. Background technique [0002] Mechanical properties such as tension, compression, and bending are common items in the testing of mechanical properties of materials, which can reflect the mechanical properties of materials to a large extent, and are of great significance to the research of materials. Some existing mechanical testing equipment can only perform tensile and / or compressive performance testing, and additional equipment is required for bending performance testing; and usually can only perform mechanical testing under normal temperature and normal pressure environments. Mechanical properties under other temperature and pressure conditions cannot be achieved by these devices. For example, patent CN207439306U discloses a portable tensile test post-breaking productivi...
