FEM-Based Secondary Development of Geo-Material Constitutive and its Application

Abstract:

For the reason of clear conception and simple physical meaning, Duncan-Chang is applied widely in civil engineering field. With the user material subroutine UMAT provided by the FEM software ABAQUS and Fortran language for programming of Duncan-Chang nonlinearity constitutive model, we can easily express the nonlinearity of rock and soil. Meanwhile, the model is applied in sedimentation analysis of high embankment. The results indicate that there is the most horizontal displacement in about middle embankment height; there is the most vertical displacement in about (1/3~1/2) embankment height; there are the most major stress and minor stress in deepest place.
