Numerical analysis on crushing stress of sand in ...
The constitutive for sand with particle crushing is established based on the critical state theory. The stress-dilatancy equation of this model is the same as that of modi ed Cam-clay model. The yield function of constitutive model for sand with particle crushing is given in Eq. (7). f= Ct Ce pm a (2n+ 1)p2n c M2 q2 p +p2n+1 m 2n+1 pm o
