2. Working principle of creep testing machine
The creep testing machine completes the test through the following steps:
1.Loading stress: Apply constant tensile, compressive or bending stress to the specimen.
2.control temperature: Place the sample in a constant temperature environment to simulate high or low temperature conditions.
3.Measure deformation: Record the deformation of the sample over time through a high-precision sensor.
4.data analysis: Generate a creep curve to evaluate the creep resistance of the material.
