Definition

An anisotropic yield model that generalizes isotropic quadratic yield criteria by introducing directional coefficients to represent different yielding behavior along material axes; it predicts yield when a specified quadratic form of the stress components — weighted by anisotropy parameters — reaches a critical value tied to the material’s directional yield strengths.
