This paper presents a numerical and experimental study on the single-abrasive scratching
of BK7 glass. The formation mechanisms of cracks are investigated for surface integrity …

Rock cutting typically involves driving a rigid cutter across the rock surface at certain depth of
cut and is used to remove rock material in various engineering applications. It has been …

Because of the outstanding advantages in studying crack propagation and coalescence of
brittle solids, the discrete element method (DEM) has been widely used to study the crack …

Barium osumilite (BMAS) ceramic matrix composites reinforced with SiC‐Tyranno fibers are
tested in a cyclic loading protocol. Broadband acoustic emission (AE) sensors are used for …

The high hardness and brittleness of engineering ceramics make it difficult to ensure surface
quality during conventional grinding. Compressive pre-stress assisted machining, as a new …

This paper reports an approach to use the acoustic emission (AE) technology for monitoring
the surface/subsurface damage in twodimensional pre-stress scratching of SiC ceramics, in …

Indentation and scratch models are proposed to numerically investigate effects of
compressive prestress on film's mechanical responses. In indentation, normal stress …

A stress field model was built to study the effects of pre-stressing value, normal and
tangential load on the three principal stresses and maximum shear stress when the silicon …
