A high-temperature in-situ loaded computed tomography (CT) testing system based on a laboratory X-ray source and a method therefor are provided. A dynamic sealing device is adopted. A pull-up pressure rod and a pull-down pressure rod are allowed to rotate circumferentially and move axially. Meanwhile, a high-temperature furnace is fixed without rotating or moving, such that the high-temperature furnace is flat in an imaging direction to shorten an imaging distance and improve imaging quality. An independent tensile testing machine is utilized to achieve high-load loading. The in-situ measurement of internal deformation and damage information of a specimen under tensile or compressive load in a high-temperature environment is implemented. By taking advantage of the miniaturization design of the high-temperature device, the accuracy of the damage test using the laboratory X-ray source is increased. Tests and researches on the internal damage and failure behavior of the high-temperature materials can be conducted.

In a stress measurement method, an object to be measured is vibrated at a plurality of oscillation frequencies, and a temperature amplitude of the object to be measured is measured by using a temperature sensor. Parameters of a one-dimensional heat conduction equation described below are identified by performing curve-fitting, on the basis of the one-dimensional heat conduction equation, on a measurement value of the temperature amplitude with respect to frequency characteristics of a temperature change component and a phase component based on a thermoelastic effect. The frequency characteristics are obtained at the plurality of oscillation frequencies. The one-dimensional heat conduction equation indicates a theoretical solution of a temperature amplitude on a surface of a coating film based on heat conduction and the thermoelastic effect of each of a substrate and the coating film. Then, a stress of the object to be measured is obtained based on the identified parameters.
