TL;DR: In this article, a diamond abrasive grain was modeled by a cubo-octahedron that was determined by the intersection between an octahedral and a cube, and the results showed that the predicted morphology of grinding wheels agreed well with the experimentally measured.

TL;DR: In this paper, the effect of O2 on the nano-indentation of diamond cubic silicon using molecular dynamics simulation was explored with the aid of the Tersoff potential for Si-Si interactions and the Morse potential for all other interactions, and the results showed that O2 molecule in the appropriate position and orientation dissociates into oxygen atoms, penetrates into the subsurface region and forms chemical bonds with silicon atoms.

TL;DR: In this article, a new formula for the contact length prediction is proposed, and a simple criterion to determine the applicable range of any approximate formulae, and then carefully compare our formula with available models, discuss their characteristics and limitations in application.

TL;DR: In previous investigations on the cutting of ceramic particle reinforced metal matrix composites using the finite element (FE) method, the particles are usually considered to be rigid as mentioned in this paper, which is inco...

TL;DR: A brief review of some of the key aspects of abrasive polishing, including adaptability and sustainability of artificial materials to human body, selection of materials, precision fabrication and efficient replacement operation are provided.
