In this article, the stress distribution of the round hole of the typical testing piece is simulated by finite element analysis software - ANSYS. Through contrast analysis between finite element result and analytic solution, the reliability and accuracy of ANSYS calculation are proved, which provides an important means for the further research into the relationship between stress distribution and flux leakage field in typical testing piece and perfection of the theoretical basis of magnetic memory testing.
