WebHill [11] proposed a yield criterion for anisotropic materials by introducing six anisotropic parameters in the von Mises yield criterion. Different from the quadratic form of yield criterions mentioned above, some non-quadratic yield criterions [12], [13], [14] are also proposed to describe the anisotropic behavior in yielding. ... WebAug 1, 2024 · In Fig. 5, the yield locus projected on the zero shear stress plane, τ xy = 0, is shown for Hill's 1948, Barlat yld2000 and the new quadratic yield function (the stresses are normalised from the uniaxial stress at 0 degrees (σ 0)).It can be seen that the new yield function delivers a yield locus which is almost coincident with the yield locus from Barlat …
WebThe yield surface is defined by Hill's criterion, with the generalized norm ‖ a ˜ ‖ H = (a ˜: H ˜ ˜: a ˜) 1 / 2, which reduces to the von Mises yield criterion in the isotropic case, with ‖ a ˜ ‖ … Webhigh-yield - yielding a large amount of agricultural or industrial production fruitful - productive or conducive to producing in abundance; "be...
