웹2024년 11월 23일 · The Barlat2000 model gives the most accurate representation of the yield surface especially for larger plastic strain ranges. The recommendations for accurate prediction of springback in monolithic metals made in the mentioned references is extended to metal-polymer-metal sandwich in this study. 웹The results show that Barlat2000 yield criterion can well describe anisotropy yield locus in tensile test for AZ31B sheet at various temperatures. Yld2000-2D should be very well received by FE implementers and users for numerical simulations of sheet forming processes because of its accuracy and simplicity.
