This paper presents an unconstrained stress updating algorithm for a critical state plastic
model of clay soil, where the loading/unloading estimations and the consideration of the …

The need of accurately reproducing the behaviour of elastoplastic materials in
computational environments for the solution of engineering problems motivates the …

Abstract Most existing Finite Element Method and the Material Point Method (FEM-MPM)
coupling is designed for explicit solvers. By contrast, implicit schemes offer the advantage of …

In this paper, an actual landslide process that occurred in Southern China is simulated by a
continuum approach, the particle finite element method (PFEM). The PFEM attempts to solve …

The governing equations of the variational approach to brittle and ductile fracture emerge
from the minimization of a non-convex energy functional subject to irreversibility constraints …

Consequences of submarine landslides include both their direct impact on offshore
infrastructure, such as subsea electric cables and gas/oil pipelines, and their indirect impact …

A version of the Particle Finite Element Method applicable to geomechanics applications is
presented. A simple rigid-plastic material model is adopted and the governing equations are …

A parametric study of undrained stability of a spherical cavity in clays is investigated by finite
element limit analysis with an axisymmetric condition. Influences of cover depth ratio of …

The particle finite element method (PFEM) is a robust approach for modelling large
deformation problems with free surface evolution. The classical PFEM, however, requires …

Recently, Krabbenhøft et al.(Int. J. Solids Struct. 2007; 44: 1533–1549) have presented a
formulation of the three-dimensional Mohr–Coulomb criterion in terms of positive-definite …
