| 英文摘要 | Smoothed particle finite element method has been gaining recognition as an appropriate approach for large deformation problems in geotechnics. This paper presents formulations for coupled large deformation problems in geotechnics within the framework of SPFEM. Emphasis is put on the incompressibility associated with the undrained limit. To stabilize the pore water pressure field, the polynomial pressure projection (PPP) formulations for SPFEM are derived. The accuracy and effectiveness of the present formulations are verified against several benchmark consolidation problems. Results show that spurious oscillations associated with the utilization of equal-order interpolants for both the solid displacement and the fluid pressure can be effectively avoided. The coupled SPFEM with PPP provides a stable and efficient numerical tool in solving coupled large deformation problems in geotechnics. |
