Abstract It is necessary to implement the yield criterion we need into the finite element software and verify the correctness of the implementation of the yield criterion. And so far, the method for verifying the correctness of the implementation of the yield criterions has not been reported. In this paper, Yld2000-2d yield criterion is implemented into ABAQUS commercial finite element software. A method which can effectively verify the correctness of the yield criterion implementation is proposed based on strict mechanical deduction. For 5754O aluminum alloy sheet, the correctness of the implementation of Yld2000-2d yield criterion into ABAQUS finite element software is verified.
