A Smooth Partition of Unity Finite Element Method for Vortex Particle Regularization [PDF]
SIAM Journal on Scientific Computing, 2017 We present a new class of $C^\infty$-smooth finite element spaces on Cartesian grids, based on a partition of unity approach. We use these spaces to construct smooth approximations of particle fields, i.e., finite sums of weighted Dirac deltas. In order to use the spaces on general domains, we propose a fictitious domain formulation, together with a ...

A higher order control volume based finite element method to prodict the deformation of heterogeneous materials [PDF]
, 2013 Materials with obvious internal structure can exhibit behaviour, under loading, that cannot be described by classical elasticity. It is therefore important to develop computational tools incorporating appropriate constitutive theories that can capture ...

Seakeeping with the semi-Lagrangian particle finite element method [PDF]
Computational Particle Mechanics, 2017 The application of the semi-Lagrangian Particle Finite Element Method (SL–PFEM) for the seakeeping sim-ulation of the Wave Adaptive Modular Vehicle under spray generating conditions is presented. The time integration of the Lagrangian advection is done using the explicit integra-tion of the velocity and acceleration along the streamlines (X-IVAS ...

Fast quasi-implicit NOSB peridynamic simulation based on FIRE algorithm
Mechanical Engineering Journal, 2019 The peridynamics is a particle methods considered superior to the finite element method in describing fracture phenomena since fracture can be simply expressed as bond breaking between the peridynamics particles.

Journal of Rock Mechanics and Geotechnical Engineering, 2022 The possibilities of the particle finite element method (PFEM) for modeling geotechnical problems are increasingly evident. PFEM is a numerical approach to solve large displacement and large strain continuum problems that are beyond the capabilities of ...
