Modeling of Free Surface Flows with Elastic Bodies Interactions [PDF]
, 2008 In this paper, a series of new fluid and structure interactions test cases with strong free surface effects are presented and computations of such flows with the Particle Finite Element Method (PFEM) (Idelsohn, Oiiate, Del Pin and Calvo, 2006) are ...

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.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 ...

Modeling of surface wear by the particle finite element method: application to tunneling processes [PDF]
, 2009 This work introduces the advances in the Particle Finite Element Method (PFEM) for the modeling of contact and wear between solid materials. The PFEM is an original conjunction of solution strategies.

Cut-PFEM: a Particle Finite Element Method using unfitted boundary meshes
Engineering with ComputersAbstractIn this work, we present a novel unfitted mesh boundary strategy in the context of the Particle Finite Flement Method (PFEM) aiming to improve endemic limitations of the PFEM relative to boundary conditions treatment and mass conservation. In this new methodology, which we called Cut-PFEM, the fluid–wall interaction is not performed by adding ...

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 4, December 2025.ABSTRACT In industrial manufacturing, large share of machining tools are produced using materials such as tungsten carbide, due to their exceptional properties. However, they are now classified as critical, due to the limited availability of constituents and the accompanying social‐environmental concerns related to their mining and processing.

Proceedings in Applied Mathematics and Mechanics, Volume 19, Issue 1, November 2019., 2019 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
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 8, Page 1931-1947, 10 June 2025.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.

Aspects of the Particle Finite Element Method applied to contact problems
Proceedings in Applied Mathematics and Mechanics, Volume 19, Issue 1, November 2019., 2019 Abstract The Particle Finite Element Method (PFEM) developed by [1] is designed to allow changes in the outer shape of a body while performing a Finite Element Analysis. This is achieved by repeated remeshing and shape detection of a particle cloud, which represents the body under consideration.

A Fully Coupled Formulation For Incompressible Fluid-Elastic Structure-Interactions [PDF]
, 2005 We present a general formulation for analysis of fluid flows with structural interactions using the particle finite element method (PFEM). The fluids are fully coupled to the structures that can undergo highly non-linear response due to large ...
