Introduction

Industrial components are subjected to different forms of multi-axial fatigue loads, and fatigue cracks usually originate from surface defects or geometric discontinuities of the components. Continuation, so its fatigue performance is mainly affected by the plane biaxial stress state. The biaxial stress state includes the magnitude of the principal stress in the plane and the sign phase The equal double tension state (existing in internal pressure, torsion and thermal load tests), the pure shear state with the same in-plane principal stress and the opposite sign (such as Torsion and pure shear test) and the biaxial stress state in between. Because the uniaxial test is simple and low-cost, the global fatigue test data is mostly carried out in the uniaxial state. Therefore, another objective of multi-axis testing The goal is to develop a material mechanics model to realize the correlation between multi-axis and single-axis under specific conditions. In order to ensure the reliability and consistency of multi-axial fatigue test research in different laboratories, in the process of testing and collecting data The relevant recommendations and regulations of this document should be followed.
