19] measured such dilatancy
peak on plastisols at intermediate shear rates.
During compression in different confining pressure, the volume strain is always characterizes negative and positive dilatancy
The pressure sensitive yield function will give plastic dilatancy
when the associated flow rule is assumed.
And the strain of shear dilatancy
is smaller than the strain of peak strength.
To complete the description of the constitutive model, evolution of the hardening modulus H and dilatancy
[beta] must still be explained.
When the proportion of fines is 40%, there is an increase in the deviatoric stress, which is due to the role of the fines in increasing the dilatancy
in the soil and the absence of a contractile phase.
The Mohr-Coulomb model has 5 parameters: The Young's modulus (E), The Poisson's ratio (u), cohesion (c), friction angle ([phi]'c) and the dilatancy
In addition, there are two parameters, which define the failure criteria (the friction angle, [phi], and cohesion, c) and a dilatancy
angle, [psi], which to describe the flow rule.

This model involves five parameters: Young's modulus E, Poisson's ratio v, cohesion c, friction angle [phi], and the dilatancy
