A Modeling Approach for Predicting the Abrasive Particle

A Modeling Approach for Predicting the Abrasive Particle Motion During Chemical Mechanical Polishing Chemical mechanical polishing (CMP) is a manufacturing process in which a wafer surface is polished by pressing it against a rotating pad that is flooded with slurry. The slurry itself is a fluid containing abrasive particles.

A numerical approach for the evaluation of particle-induced

An Euler-Lagrange coupling based on this multiscale approach is used in the present contribution in order to perform a computationally-efficient simulation. Computational feasibility is a crucial aspect of the proposed method, as a purely numerical model for the prediction of particle-induced erosion must bridge a wide range of time scales. 2.2.

predicting abrasive wear with coupled lagrangian methods

Predicting abrasive wear with coupled Lagrangian methods

In this paper, a mesh-less approach for the simulation of a fluid with particle loading and the prediction of abrasive wear is presented. We are using the smoothed particle hydrodynamics (SPH) method for modeling the fluid and the discrete element method (DEM) for the solid particles, which represent the loading of the fluid. These Lagrangian methods are used to describe heavily sloshing

A Full Wafer-Scale PAML Modeling Approach for Predicting CMP

These abrasives are suspended in a liquid medium and transported across the interface to provide even material removal. The current model presents an expansive wafer-scale framework that not only accounts for the solid–solid contact mechanics and wear, but also utilizes the mechanics of the slurry through fluid and particle dynamics.

(538e) Exploring the Particle Augmented Mixed Lubrication

Predicting slurry tribology requires an understanding of multiple modes of mechanics, namely the fluid mechanics, particle mechanics, contact mechanics, and the mechanics of material wear. This work describes a new multi-physics, slurry tribology modeling framework called particle augmented mixed lubrication (PAML).

A Finite Element Approach to Modeling Abrasive Wear Modes

Abrasive wear; wear modeling; abrasive wear types Introduction Abrasive wear of machine components is a problem for equip-ment operating in sandy environments. The damage inflicted on, for example, plain and roller bearings affects the perfor-mance of the machine, reducing maintenance intervals and ultimately leading to failure.
