Numerical modelling of landslides in reservoirs via the Particle Finite Element Method (PFEM)
The paper presents the results of the application of the Particle Finite Element Method (PFEM) to the analysis of landslides in reservoirs. This is a complex phenomenon, because of the interaction between the landslide, the still water in the reservoir and the dam.

Many polymer-made objects show a trend of melting and dripping in fire, a behavior that may be modified by adding flame retardants (FRs). These affect materials properties, e.g., heat absorption and viscosity.

On the application of Particle Finite Element Method (PFEM) to problems in civil engineering [PDF]
Current chapter tries to give an overview of theoretic background necessary to deal with fluid dynamic problems with Finite Element Method (PFEM) approach. Starting form a brief summary of the principle steps of the development of the theory, we analyze the differences between the classical world of fluids, finding out finally the principle ...

Modeling Grinding Processes—Mesh or Mesh-Free Methods, 2D or 3D Approach?
The objectives of this study are mainly two: (1) to validate whether a single grain scratch process can be modeled in two dimensions under the assumption of plane strain, and (2) to select the best discretization approach to model a single grain scratch ...

An implicit locking‐free B‐spline Material Point Method for large strain geotechnical modelling
Abstract The Material Point Method (MPM) has drawn great attention in the numerical modelling of large deformation, geotechnical problems. The popularity of MPM is mainly because its formulation shares significant similarities with the Finite Element Method.

The surface‐reconstruction virtual‐region mesh update method for problems with topology changes
Abstract In this work, we introduce a novel boundary‐conforming mesh‐update method that is particularly designed for problems with large boundary displacements and topology changes. This method, which we call the surface‐reconstruction virtual‐region mesh update method, integrates the virtual region approach and a surface reconstruction process to ...

Abstract Continuous technological advancements in the field of grinding technology and improved grinding tools have contributed to the development of high performance grinding processes. One example of such a process is internal traverse grinding (ITG) with electroplated cBN grinding wheels, where the tool consists of a conical roughing zone and a ...

Sediment transport problems by the particle finite element method (PFEM)
This paper presents a particle finite element model for the numerical simulation of sediment transport problems. Fluid motion and sediment motion are coupled in a two-way manner, through boundary shear stress field and through flow domain mesh deformation.
