The Hill yield criterion developed by Rodney Hill, is one of several yield criteria for describing anisotropic plastic deformations. The earliest version was a straightforward extension of the von Mises yield criterion and had a quadratic form. This model was later generalized by allowing for an exponent m. … See more The quadratic Hill yield criterion has the form Here F, G, H, L, M, N are constants that have to be determined experimentally and Expressions for F, G, … See more In 1993, Hill proposed another yield criterion for plane stress problems with planar anisotropy. The Hill93 criterion has the form See more • Yield criteria for aluminum See more The generalized Hill yield criterion has the form where $${\displaystyle \sigma _{i}}$$ are the principal stresses (which are aligned with the directions of anisotropy), Generalized Hill … See more The original versions of Hill's yield criterion were designed for material that did not have pressure-dependent yield surfaces which are needed to model polymers and foams. The Caddell–Raghava–Atkins yield criterion See more WebOct 28, 2024 · In this paper, the evolution of the anisotropic behavior of a DC04 sheet during work hardening is analyzed based on a quadratic Hill48 function and under the application of two plasticity ... philippine outreach program 2022 florida
