Description

technical field [0001] The invention belongs to testing instruments, and relates to a displacement measuring system, in particular to a dynamic airtight automatic deformation testing system of a high temperature tester. Background technique [0002] High-temperature compressive strain, three-point bending stress-strain, load softening temperature, compressive creep, thermal expansion and other deformation-related testing techniques of materials all need to test the deformation of materials under the action of heat, force, and time duration. [0003] High-temperature three-point bending stress-strain is to apply three-point bending stress to the sample at a certain temperature at a certain constant stress or constant displacement increase rate, and the sample will produce bending deformation with the increase of stress. Point bending stress-strains are interrelated and dependent. [0004] High-temperature compressive stress-strain is to apply compressive stress to the sample...
