An Investigation into the Influence of the Contact Pressure Distribution at the Friction Pair Interface on Disc Brake Squeal [PDF]

open access: yes
The main purpose of this thesis is to investigate the dynamic centre of pressure during a noisy brake application. A novel technique is employed to measure the centre of pressure and contact pressure distribution between the disc/pad interfaces during ...

PTFE/carbon composite radial deep groove ball bearings: Part 1–tribological characterization suitable for ball bearing applications

open access: yesPolymers and Polymer Composites
Polytetrafluoroethylene (PTFE) is a self-lubricating, highly stable, high-performing polymer that has expanded its usage in bearing tribology. However, its application in ball bearings is still limited.

Work Hardening and Change in Contact Condition of Rolling Contact Surface with Plastic Deformation

open access: yesTribology Online, 2009
Machine designers are sometimes confronted with high contact pressure conditions which generate plastic deformation. However there is no clear design method for such severe condition.

Microstructural analysis of wear mechanisms of single-and multi-layercoatings based on the tin and a-C:H composition [PDF]

open access: yesProblemy Eksploatacji, 2011
Single layered TiN coating was characterized by a columnar structure witha large number of dislocations. a-C: H coating was completely amorphous.Multi-layer TiN/a-C:H coating was built of TiN and a-C:H layers placed in asequence way.

Computational simulation of the intervertebral disc [PDF]

open access: yes, 2013
The intervertebral disc is a complex structure unlike any other in the human body. The capability to withstand high loads and deformations in six degrees of freedom is facilitated by the unique soft tissue structures. However, the mechanical behaviour of

Two-body abrasive wear behavior of woven basalt fabric reinforced epoxy and polyester composites

open access: yesMaterials Research Express, 2020
The current research work focused on the abrasive wear behavior of the basalt fabric as reinforcement in epoxy and polyester composites. Traditional hand-layup technique is used to manufacture the composites.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

The ball embedding property of the open unit disc

open access: yes, 2011
We prove that the open unit disc Delta in C satisfies the ball embedding property in C(2); i.e., given any discrete set of discs in C(2) there exists a proper holomorphic embedding Delta hooked right arrow C(2) which passes arbitrarily close to the discs.
