WebAug 17, 2016 · If so, is there an analytical solution for computing yield stress in ANY direction knowing yield stresses in reference frame? I.e. is yield stress of 'tensorial' quality, meaning - knowing anisotropic state any coordinate frame can be used to express criterion? Is Hill48 thermodynamically admissible if it can be expressed only in a specific frame? 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 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 See more The generalized Hill yield criterion has the form where $${\displaystyle \sigma _{i}}$$ are the principal … See more In 1993, Hill proposed another yield criterion for plane stress problems with planar anisotropy.
