doi:10.3901/JME.2023.20.179

Abstract

Abstract: In the core fields of aerospace, nuclear industry, marine engineering, and rail transportation, the demand for fatigue testing under complex service conditions of many key structural component materials has promoted the continuous development of multi-axial fatigue testing technology. This paper firstly reviews the development of traditional multiaxial fatigue test techniques, including tensile-torsion, bending-torsion, tensile-bending, biaxial tensile, biaxial bending, and tensile-bending-torsion. Subsequently, the newly developed multiaxial ultrasonic fatigue testing techniques containing biaxial tensile, biaxial bending, tensile-torsion, and tensile-bending-torsion in the last decade are reviewed. In addition, the key issues of stress assessment, specimen cooling, frequency effect, and size effect in ultrasonic fatigue testing are summarized and the corresponding solutions are given. Finally, the application of the above multiaxial fatigue testing techniques in typical materials, titanium alloys and nickel-based superalloys, is briefly introduced. Based on the summary, the development direction of multi-axial fatigue testing techniques for materials is proposed, and new opportunities for future development in this field are pointed out.

Key words: multi-axis fatigue, test technique, ultrasonic fatigue
