Abstract
The experimental approach to analyze the direct correlation between the plastic pileup and the plastic strain of the Vickers indentation test was presented. The correlation between the yield strain and the plastic pileup was analyzed through the interrupted tensile test of SUS316L, the stainless steel in which the strain hardening phenomenon one of the two major factors affecting the plastic pileup is fixed. Finally, it was checked that the plastic strain is the parameter directly affecting the plastic pileup and that the relation through the linear function can be analyzed. Moreover, as for the depth of the indentation test, it was also checked that the plastic pileup can be corrected through the factor.
