Measuring Residual Stress of 304 Austenitic Stainless Steel by Spherical Indentation
In this study, we have used the FE method to investigate the effect of in-plane residual stress and strain-hardening exponent on the indenter load, indentation work and residual depth. Based on the reverse analysis, the 304 stainless steel’s residual stress and strain-hardening exponent can be measured fromone simple indentation test by using spherical indenter. The comparison between residual stress or strain-hardening predicted from reverse analysis and the input residual stress or strain-hardening used in numerical indentation experiments shows good agreement.
