Fluid–structure interaction using the particle finite element method [PDF]
Computer Methods in Applied Mechanics and Engineering, 2006 In the present work a new approach to solve fluid-structure interaction problems is described. Both, the equations of motion for fluids and for solids have been approximated using a material (lagrangian) formulation. To approximate the partial differential equations representing the fluid motion, the shape functions introduced by the Meshless Finite ...

Journal of Rock Mechanics and Geotechnical Engineering, 2023 In this paper, the application of Abaqus-based particle finite element method (PFEM) is extended from static to dynamic large deformation. The PFEM is based on periodic mesh regeneration with Delaunay triangulation to avoid mesh distortion.

Modeling of Ground Excavation with the Particle Finite-Element Method [PDF]
Journal of Engineering Mechanics, 2010 An excavation process is a nonlinear dynamic problem that includes geometrical, material, and contact nonlinearities. The simulation of ground excavation has to face contact interaction in a changing geometry composed by several solid domains. The particle finite-element method (PFEM) is based on a Lagrangian description for modeling the motion of a ...

Enrichment of the Finite Element Method With the Reproducing Kernel Particle Method [PDF]
Journal of Applied Mechanics, 1997 The reproducing kernel particle method (RKPM) has attractive properties in handling high gradients, concentrated forces, and large deformations where other widely implemented methodologies fail. In the present work, a multiple field computational procedure is devised to enrich the finite element method with RKPM, and RKPM with analytical functions. The

Possibilities of the Particle Finite Element Method in Computational Mechanics [PDF]
, 2010 We present some developments in the formulation of the Particle Finite Element Method (PFEM) for analysis of complex coupled problems in fluid and solid mechanics accounting for fluid-structure interaction and coupled thermal effects. The PFEM uses an updated Lagrangian description to model the motion of nodes (particles) in both the fluid and the ...
