This paper uses the method of tensor to proof the tenable condition of generalized plastic potential, discuss the mathematical essential of the associated and disassociated flow rule and the relation of the yield surface and plastic potential surface, reason the expression of plastic factor strictly. debate the limitation on drucker ' s postulate. subsequently, this paper gives the mathematical basis of constitutive theory involving the rotation of principal stress axes. so it is proved that the mathematical and mechanical foundation of the generalized plastic mechanic
本文運用張量的方法論證了廣義塑性位勢理論成立的充要條件，討論了關聯與非關聯流到法則的數學實質，屈服面與塑性勢面的關系，嚴密推導了塑性因子的表達式，討論了drucker公設的局限性，並給出了考慮主應力軸旋轉時土體本構模型理論的數學依據，系統的論證了廣義塑性力學成立的數學力學基礎。 -
