WebIn 1993, Hill proposed another yield criterion for plane stress problems with planar anisotropy. The Hill93 criterion has the form. where is the uniaxial tensile yield stress in the rolling direction, is the uniaxial tensile yield stress in the direction normal to the rolling direction, is the yield stress under uniform biaxial tension, and are ... WebRodney Hill has developed several yield criteria for 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.Variations of these criteria are in wide use for metals, polymers, and certain composites. cisco can\u0027t find the store for remote file https://armtecinc.com
