: These rules describe how the yield surface evolves as the material deforms.

: The yield surface shifts its position in stress space, often used to model the Bauschinger effect in cyclic loading. fundamentals of plasticity in geomechanics pdf

: Assumes the plastic strain increment is normal to the yield surface (Normality Rule), common in metal plasticity but often less accurate for frictional materials like soil. : These rules describe how the yield surface
