Abstract: | In this paper, some practical aspects of the finite element implementation of critical state models are discussed. Improved
automatic algorithms for stress integration and load and time stepping are presented. The implementation of two generalized
critical state soil models, with one described first in this paper and the other recently published elsewhere, is discussed.
The robustness and correctness of the proposed numerical algorithms are illustrated through both coupled and uncoupled analyses
of geotechnical problems. |
