Research on decoupling conditions for elastoplastic consolidation with numerical modeling method
A decoupled method for elastoplastic consolidation is investigated. Firstly
an elastoplastic constitutive model is constructed based on numerical modeling method. Moreover
the uniform matrix expression of the model for axisymmetric and plane strain problems is deduced. The model is applied to Biot consolidation theory. Then the incremental governing partial differential equations are established by using this method. According to stress paths
the decoupled conditions of these equations are discussed. Based on that
a diffusion equation and uncoupling governing equations are presented. Moreover
the method is applied to numerical analyses of two examples. It was indicated that this method is reasonable
