TL;DR: In this article, the authors investigated the fiber fracture mechanisms during the elliptic vibration-assisted (EVA) cutting of fiber-reinforced polymer (FRP) composites and found that bending-dominated fracture is prevalent above the cutting path.

TL;DR: In this paper, the authors discussed the cracking in monocrystalline silicon induced by microindentation with spherical and Berkovich indenters and scratching and found that cracks always commenced in a specimen's subsurface beneath the transformation zone.

TL;DR: In this article, a three-dimensional kinematic simulation of surface topography ground by a D301 electroplated diamond wheel is presented, and the predicted surface roughness is close to the theoretical and experimental values with relative errors of − 7.9% and − 3.3% for aluminum and fused silica, respectively.

TL;DR: In this paper, the authors investigated the dynamic friction method for single crystal diamond polishing and found that by selecting a proper polishing pressure and sliding speed, a very high polishing rate at 10,300 µm/h (or 28 X 10-2 mg/s) with a high quality surface finish can be reached, which is hundreds times faster than the other polishing process reported in the literature.

TL;DR: In this paper, a model of a single sapphire wafer was developed to analyze the transient heat conduction in conjunction with the heat radiation and heat convection on the wafer surfaces.
