What is a fatigue creep testing machine?
In the fields of industrial manufacturing, materials science and engineering, fatigue creep testing machines are important testing equipment used to evaluate the performance of materials under long-term loading. This article will introduce in detail the definition, working principle, application fields, and recent hot topics and hot content of the fatigue creep testing machine.
1. Definition of fatigue creep testing machine
The fatigue creep testing machine is a device used to test the fatigue performance and creep performance of materials under cyclic loading or constant load. Fatigue performance refers to the accumulation of damage in a material during repeated loading and unloading, while creep performance refers to the slow deformation of a material under constant stress over a long period of time.
2. Working principle of fatigue creep testing machine
The fatigue creep testing machine simulates the stress conditions of materials in actual use by applying controlled loads (such as tension, compression, bending, etc.). Equipment is usually equipped with high-precision sensors and data acquisition systems that can record material deformation, stress, strain and other parameters in real time.
| Test type | Loading method | Typical parameters |
|---|---|---|
| Fatigue test | Cycle loading | Frequency, amplitude, number of cycles |
| Creep test | constant loading | stress, temperature, time |
