| Abstract: | This paper systematically presents the research work of authors in strain space formulated geotechnical elasto-plastic theory and its numerical method. The following aspects are mainly discussed: the advantages of the theory, the transferring relations between stress space and strain space, the generalized yield criteria, the uniform loading criteria, the flow rule and the constitutive relations and initial stress method (or initial strain method) in strain space. Furthermore, a finite element program based on this theory has been compiled. Two numerical examples are given which proved that the proposed theory and method are not only simple and convenient but also practical. It opens up a path for the application of strain space theory in the geotechnical engineering. |
