It contains the criteria of von Mises (circle in the formula_125-plane, formula_128, formula_129), Tresca (regular hexagon, formula_130, formula_131), Mariotte (regular triangle, formula_132, formula_131), Ivlev (regular triangle, formula_134, formula_131) and also the cubic criterion of Sayir (the Ottosen criterion ) with formula_136 and the isotoxal (equilateral) hexagons of the Capurso criterion with formula_131. The von Mises - Tresca transition follows with formula_130, formula_139. The isogonal (equiangular) hexagons of the Haythornthwaite criterion containing the Schmidt-Ishlinsky criterion (regular hexagon) cannot be described with the Podgórski ctiterion.
