ParabolicCC
Parabolic Hardening Modified Cam-Clay Model
Theory
This model defines a parabolic hardening rule for , which is a non-negative function.
in which is the hardening modulus, note is the
volumetric plastic strain.
The hardening modulus could be either positive or negative.
This hardening rule does not imply any physical soil behavior.
