The Mean Stress as the Governing Parameter in the Implicit GPM Stress Integration of Modified Cam-Clay Model
Abstract
An implicit computational governing parameter method (GPM) for stress integration of the modified Cam-Clay model is presented in the paper. In the previous studies, the increment of the mean plastic strain d epsilon(p)(m) was adopted as the governing parameter for the modified Cam-Clay model. While in this paper, the effective mean stress sigma(m)' is used as the governing parameter, which is much more convenient than d epsilon(p)(m). Such algorithm is simple, reliable, efficient and robust. This approach makes it possible to calculate the true tangent constitutive matrix in a simple way.
