, Lanzhou University, Lanzhou 730000, China; 3. Air Force Engineering Design and Research Bureau, Beijing 100077, China) Abstract: Equivalent Mohr-Coulomb yield criterion was established, and the relationship between different constitutive models was studied. The application of equivalent Mohr-Coulomb yield criterion in Ansys was achieved by means of transforming material parameters. The stability......
