Scratch Behaviour of Bulk Silicon Nitride Ceramics

Micromachines, 2021
Si3N4 ceramic is generally recognized as being difficult to machine due to its hardness and brittleness. It is necessary to control the normal load applied and the machined depth of the abrasive particles in order to eliminate surface/subsurface damage ...

Mechanical properties of gray and white matter brain tissue by indentation

Journal of The Mechanical Behavior of Biomedical Materials, 2015
The mammalian brain is composed of an outer layer of gray matter, consisting of cell bodies, dendrites, and unmyelinated axons, and an inner core of white matter, consisting primarily of myelinated axons.

Modelling of low-energy/low-velocity impact on Nomex honeycomb sandwich structures with metallic skins [PDF]

, 2008
In the aircraft industry, manufacturers have to decide quickly whether an impacted sandwich needs repairing or not. Certain computation tools exist at present but they are very time-consuming and they also fail to perfectly model the physical phenomena ...

Comparative study of abrasion via microindentation and microscratch tests of reinforced and unreinforced lamellar cast iron

Friction, 2018
This study compares micro-abrasive wear in two kinds of grey cast iron. Classical lamellar cast iron with fully pearlitic matrix (FGL1) and lamellar micro-alloyed cast iron with phosphorus and boron (FGL2) are used.
