Three Dimensional Implementation of HISS Model in ABAQUS
The yield surface of hierarchical single surface (HISS) model is a single smooth function, which overcomes the singularity of so-called cap model. The HISS model and the main parameters influence on the yield surface were introduced. Tests on one Gauss Point are produced by MATLAB, and the stress path and yield surface are measured during loading process. Based on the further development platform provided by ABAQUS, the HISS model was programmed into a three dimensional user-material subroutine (UMAT). Three kinds of triaxial tests (HC, TC and TE) and several proportional loading tests of Munich sand were simulated by ABAQUS with the developed model. The stress-strain relationships obtained by ABAQUS were compared real with experiments results. The numerical predictions show good agreement with the observed behavior in experiments, which verified the UMAT and proved the applicability of HISS model to sands. The three dimensional implementation of HISS model in ABAQUS provides the commercial FEM code a new optional constitutive law for the elastoplastic problems in soil mechanics.
