On the Numerical Modelling of Machining Processes via the Particle Finite Element Method (PFEM)

, 2015
Metal cutting or machining is a process in which a thin layer or metal, the chip, is removed by a wedge-shaped tool from a large body. Metal cutting processes are present in big industries (automotive, aerospace, home appliance, etc.) that manufacture big products, but also high tech industries where small piece but high precision is needed.

The Particle Finite Element Method (PFEM): an effective numerical technique for solving coastal engineering problems

, 2013
We present some developments in the Particle Finite Element Method (PFEM) for the solution of complex coupled problems in coastal engineering involving fluid-soil-structure interaction (FSSI) such as the stability of breakwaters and harbor constructions under sea waves, the sinking of ships and the collision of ships with ice blocks.

Numerical simulation of penetration problems in geotechnical engineering with the particle finite element method (PFEM)

, 2015
This paper highlights a computational framework for the numerical analysis of saturated soil-structure interaction problems. The variational equations of linear momentum and mass balance are obtained for the large deformation case. These equations are solved using the Particle Finite Element Method.

On the validation of the particle finite element method (PFEM) for complex engineering fluid flow problems

, 2006
Several comparisons between experiments and computational models are presented in the following pages. The objective is to verify the ability of Particle Finite Elements Methods (PFEM) [1] [2] to reproduce hydraulic phenomena involving large deformation of the fluid domain [4].

On the application of Particle Finite Element Method (PFEM) to problems in civil engineering

, 2019
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 ...

Validation of the particle finite element method (PFEM) for simulation of rock slides in lakes and reservoirs

, 2012
The analysis of landslides in reservoirs is particularly interesting because the oscillation of the water surface elevation (especially rapid drawdowns) can foster their occurrence. The existence of the reservoir for a long enough time makes the material of the slopes turn saturated, thus its pore pressure raises and, as a consequence, its effective ...
