屈服强度

Correction Cam model what go up in π plane is umbriferous it is a circle, this does not accord with numerous cliff earth kind material the experimental fact; that succumb and destroys orbit on π plane and fall in three-dimensional stress condition, lade-Duncan destroys criterion to be able to be opposite cliff earth kind material gives out to be described reasonably in the intensity on π plane and attrition character.

修正Cam模型在π平面上的投影是一个圆，这不符合众多岩土类材料在π平面上的屈服和破坏轨迹的实验事实；而在三维应力状态下，Lade-Duncan破坏准则能对岩土类材料在π平面上的强度和摩擦特性给出合理的描述。
