Enhanced cone penetration test interpretation with the Particle Finite Element Method (PFEM)
The paper presents an enhanced interpretation of the cone penetration test based on numerical analysis performed using the Particle Finite Element Method (PFEM). This method allows the incorporation of strong non-linearities, notably those associated with the large displacements and strains arising from the process of the penetration of the cone ...

Explicit‐Implicit Material Point Method for Dense Granular Flows With a Novel Regularized µ(I) Model
ABSTRACT The material point method (MPM) is widely employed to simulate granular flows. Although explicit time integration is favored in most current MPM implementations for its simplicity, it cannot rigorously incorporate the incompressible µ(I)‐rheology, an efficient model ubiquitously adopted in other particle‐based numerical methods. While operator‐

How Does Heterogeneity Control Strain Localization Patterns in High‐Porosity Rocks?
Abstract We aim to explore how heterogeneous porosity and grain size contribute to strain localization patterns in highly porous rocks based on phase‐field simulations. The strain localization patterns, including shear bands, dilatation bands, and compaction bands, are commonly observed in geological field studies and laboratory experiments.

Abstract Weathering is a fundamental driver of landslide evolution over geological timescales. Despite its ubiquity and importance, quantifying how weathering drives the progressive destabilization of rock slopes remains challenging. In this work, we develop a unified computational framework based on the particle finite element method to investigate ...

Numerical modelling of landslide-generated waves with the particle finite element method (PFEM) and a non-Newtonian flow model [PDF]
Landslide-generated impulse waves may have catastrophic consequences. The physical phenomenon is difficult to model because of the uncertainties in the kinematics of the mobilised material and to the intrinsic complexity of the fluid–soil interaction. The particle finite element method (PFEM) is a numerical scheme that has successfully been applied to ...

Abstract The properties of hardened concrete structures, fabricated by novel additive manufacturing techniques with fresh concrete, are significantly influenced by the manufacturing process. A numerical framework for the simulation of extrusion processes in additive manufacturing techniques based on layered extrusion is proposed.

Multiphase and Multiphysics Modelling of Rainfall Induced Failure in an Experimental Hillslope
ABSTRACT Annual precipitation and its intensity have increased worldwide since the start of the 20th century and represent two weather and climate change indicators related to rainfall‐induced landslides. Although these landslides can occur in a very short time, the hydro‐mechanical conditions that precede them can take several hours or days to develop.

Evaluation of cut slope stability in the Lesser Himalaya of Nepal
A spatial inventory of cut slopes in the central and western Lesser Himalaya of Nepal was prepared and characterised to evaluate their stability. The stability of these cut slopes is governed by the geotechnical properties of rock/soil together with ...

A SPH Model Bridging Solid‐ and Fluid‐Like Behaviour in Granular Materials
ABSTRACT We propose a smoothed particle hydrodynamics (SPH) model bridging the gap between solid‐ and fluid‐like behaviour observed in granular materials. The key innovation of the proposed approach lies in the decomposition of the stress gradient into rate‐independent and rate‐dependent parts, which are governed by the hypoplastic and μ(I)$\mu (I ...

The Particle Finite Element Method (PFEM) is a Lagrangian finite element method with frequent remeshing, particularly suited for the simulation of fluid motions with evolving free surfaces, e.g., in the case of breaking waves or fluid--structure ...
