In the process of metal welding, residual stress will inevitably be introduced. In the real service environment, the residual stress will also undergo further evolution and development, which will directly affect the properties of materials or components, and then threaten the safety of life and property. Therefore, it is of great practical value to study the rapid and accurate measurement method of residual stress. Traditional test methods have their limitations, thus, someone proposed that the magnitude and direction of residual stress can be characterized based on the morphology after unloading of spherical indentation. But the effect of material parameters on the pile-up morphology has not been studied. In this paper, the influence of material parameters on the indentation morphology is systematically studied by finite element simulation. The research results show that materials with a hardening index greater than 0.3 are not recommended to use this method, and the yield strength has little effect on the results.
