Exploring the accuracy of nanoindentation testing is especially important for determining the hardness and Young’s modulus values of materials. In this paper, molecular dynamics simulation was used to study the nanoindentation mechanism of three-body diamond abrasive grains rotating at various speeds on single-crystal silicon materials. An in-depth study of the three-body diamond abrasive nanoindentation...
There is an immense need to obtain high-quality surface and subsurface on brittle material owing to the advantage of its improved performance. Thus, in this paper, we proposed a mechanical and numerical study of fracture mechanics from the perspective of external loading and indentation geometry in brittle machining. Stress intensity factors are computed to analyze various impacts of external loading...
