WebFeb 12, 2024 · Hill90 and Hill93 yield criteria can represent the first and second order anomalous behaviors, but Hill90 criterion need larger CPU times in FE simulations due to its formulation and Hill93 criterion has no shear stress component . Independently from Hill’s criteria, several non-quadratic yield functions have been developed by researchers. ... WebMar 20, 2024 · Hill90 yield criterion was used, the software with implicit solver was more accurate in predicting thickness compared to software with explicit integration scheme, in most cases. In addition, the thickness prediction of parts with lower deformation was more accurate compared to parts with greater deformation (higher dome height).
