Generalized Hill Yield Criterion
The generalized Hill yield criterion has the form
where are the principal stresses (which are aligned with the directions of anisotropy), is the yield stress, and F, G, H, L, M, N are constants. The value of m is determined by the degree of anisotropy of the material and must be greater than 1 to ensure convexity of the yield surface.

You can endure the livery of a nun,

To undergo such maiden pilgrimage.”
