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

In this paper, a novel mathematical programming formulation is derived based on the up
form for the dynamic analysis of saturated porous media. A mixed finite element is used for …

This paper presents the failure analysis of layered clayey slopes with emphasis on the
combined effect of the clay's weakening behavior and the seismic loading using the particle …

Soil flow is involved in many earth surface processes such as debris flows and landslides. It
is a very challenging task to model this large deformational phenomenon because of the …

In this study, we present a novel nodal integration-based particle finite element method (N-
PFEM) designed for the dynamic analysis of saturated soils. Our approach incorporates the …

Traditional particle finite element method (PFEM) with a six-node triangular (T6) element
using an iteration algorithm often suffers from high computational costs and non …

This paper presents the nodal integration-based particle finite element method (N-PFEM) for
poro-elastoplastic analysis of saturated soils subject to large deformation, utilising the …

Accurate assessment of pipe-soil interaction under cyclic wave actions is of pronounced
importance for the stability analysis of submarine pipelines in sandy seabed. This paper …

Realistic modelling of transverse (ie vertical and lateral) pipe–soil interaction plays an
important role in predicting the behaviour of untrenched offshore pipelines that are designed …

Subsea pipelines buried in the seabed may undergo large lateral displacement under
environmental, operational, and accidental loads at different interaction rates and hence …
