The invention discloses a manual loading device for in-situ tension or compression test of industrial CT. The manual loading device is characterized by comprising a first screw, a second screw, a first nut, a second nut, a third nut, a first clamp, a second clamp, a protective cover, a first gasket, a second gasket, a steel column assembly and a tension or compression pressure sensor, wherein thefirst clamp and the second clamp are used for clamping and fixing a to-be-tested tension or compression test specimen; and the second nut or the third nut is rotated by a wrench to allow the second screw to move outwardly or inwardly, so the second clamp is driven to move outwardly or inwardly so as to apply external load on the to-be-tested test specimen. With the manual loading device of the invention, the test specimen is prevented from deformation in the process of scanning during in-situ tension or compression testing of industrial CT; and the damage evolution and destroy mechanism of a material in tension process can be evaluated based on three-dimensional cracks and fractures and other information acquired through industrial CT scanning. The manual loading device of the invention isapplicable to materials with obvious deformation during tensile fracture.
Description
technical field [0001] The invention relates to the field of material mechanical performance testing, in particular to a manual loading device for industrial CT in-situ tension and compression tests, which can be used for engineering structures such as aviation, aerospace, nuclear power, automobiles, machinery, biomedicine, materials, civil engineering, and ships. Tensile failure mechanism and mechanical performance testing of materials in the field. Background technique [0002] With the rapid development of industrial technology, non-destructive testing technology has been widely used in aerospace, automobile, shipbuilding, petrochemical, nuclear energy and other industries. Industrial CT occupies a very important position in radiographic inspection technology. It can non-destructively detect internal pores and cracks in CMC materials. The minimum voxel size can reach the nanometer level. The image information of the crack position and width can be obtained through image p...
