Definition

A yield criterion for ductile materials stating that plastic yield begins when the maximum shear stress in the material reaches the shear value measured at yield in a uniaxial tensile test; equivalently, yielding occurs when the largest difference between principal stresses attains a critical value derived from the material’s tensile yield.
