Abstract
AbstractIn this paper a novel node-based explicit smoothed particle finite element method (SPFEM), is utilized to evaluate the progressive slope failure mechanisms. In the SPFEM approach, a node integration method (strain smoothing technique) is introduced into the framework of the particle finite element method (PFEM). The main advantage of SPFEM in slope stability analysis lies in its capabilities to consider the whole dynamic failure process of slope and to simulate large deformation and post-failure of soils. The progressive failure behaviour of a long clayey slope is modelled using SPFEM in conjunction with a strain-softening Tresca constitutive model. The retrogressive failure behaviour of a long clayey slope is analyzed.KeywordsDynamicsNode integrationSmoothed particle finite element methodSlope failureProgressive failure
