  • Due to long time working in high temperature environment, there is high temperature creep deformation on some functional structural parts of active equipment, resulting in component failure, which would affect the safe use of equipment and reduce the life of equipment. Therefore, it is necessary to know the creep properties of various structural materials. Nowadays, various creep testing methods have been developed, which is of great significance for studying creep driven deformation. This article provides an overview of several creep testing methods and creep theories, including uniaxial tension, compression, and beam bending. By comparing several test methods with uniaxial tensile creep test, it is found that the fixed support three-point bending creep test can obtain a complete creep curve, and the force is simple and easy to analyze. At the same time, based on the experience of metal material bending creep testing, the high-temperature creep performance tests can be conducted on brittle materials such as glass and ceramics, which has important guiding significance.
