【摘要】 通过分析比较摩尔-库仑屈服准则与广义米塞斯准则的表达式,得出了α,k的统一表达式,并依据π平面上等效圆的面积与摩尔-库仑屈服条件的面积相等,得到了等效圆的洛德角及α,k值,实现了摩尔-库仑屈服条件与广义米塞斯条件的统一,方便了编程计算。推导了等效圆与不同D-P准则之间的函数关系,实现了摩尔-库仑准则与各种D-P准则的相互转换,使计算工作更加方便,边坡的计算实例表明该方法是可行的。更多还原

【Abstract】 This paper gives the general expressions of ακby comparing and analyzing the Mohr-coulomb yield criterion and von Mises yieldcriterion.Based on the condition that the area of equivalent circle equal to the area of Mohr-coulomb yield criterion,then Lode angle and ακof the equivalent circle is obtained,so the Mohr-coulomb yield criterion and von Mises yield criterion achiveve to unify,which makes easy pro-gram.The functional expressions relative to the equivalent area circle and D-P criterion provide a transformation between each other,whichmake calculation simpler.The results show the method mentioned above is feasible.更多还原
