    Yield Criteria
    For ductile materials, failure is often defined by yielding-the onset of permanent deformation. Common criteria include the von Mises yield criterion (for distortion energy) and the Tresca criterion (for maximum shear stress).

  2. Stress Concentration Zone

    Linked via "yielding"

    Propagation and Fatigue Implications
    When the localized stress in an SCZ exceeds the material's yield strength ($\sigmay$), localized yielding occurs. This plastic zone blunts the theoretical singularity predicted by elasticity theory. The size of this resulting process zone ($rp$) is crucial for subsequent fatigue life prediction using principles derived from the Paris Law.
