Vibration suppression of scaled-down towers in offshore wind power based on pendulum tuned particle damper. [PDF]
PLoS ONEThis paper presents a method for suppressing vibrations in a scaled wind turbine tower subjected to wind loads. The proposed approach employs a composite damping system-the Pendulum Tuned Particle Damper (PTPD). A mathematical model of the damping system

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 ...

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 ...

Multi-fluid flows with the Particle Finite Element Method [PDF]
Computer Methods in Applied Mechanics and Engineering, 2009 Particle methods are those in which the problem is represented by a discrete number of particles. Each particle moves accordingly with its own mass and the external/internal forces applied on it. In this paper the Particle Finite Element Method based on finite element shape functions is used to solve the continuous fluid mechanics equations in the case

Modeling Grinding Processes—Mesh or Mesh-Free Methods, 2D or 3D Approach?
Journal of Manufacturing and Materials Processing, 2022 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 ...
