当量应力 meaning in Chinese

equivalent stress

( 3 ) the equivalent stress , which is from the coefficients for the spectrum - loads and miner linear accumulated damage rule , an approach for material probabilistic fatigue strength for spectrum loads is suggested . this approach are established by the composed of p - c - s - n curves for extreme maximum model
( 3 )根据谱载荷系数和miner线性累积损伤准则得到的谱载荷下的当量应力的关系，与极大值模型的p - c - s - n曲线相结合，提出了谱载荷下材料概率疲劳强度的表达式。
Abstract : based on the integral creep constitutive relations of viscoelastic material with damages , a new increment finite element method to solve stress , strain and damage variables is developed by using equivalent stresses , three - dimension damage field can be analyzed and coupling stress and damage field can be solved by using iteration method
