A review of squeaking in ceramic total hip prostheses
The occurrence of audible squeaking in some patients with ceramic-on-ceramic (CoC) hip prostheses is a cause for concern. Great effort has been dedicated to understand the mechanics of the hip squeaking to gain a deeper insight into factors contributing to sound emission from CoC hip articulation. Disruption of fluid-film lubrication and friction were reported as the main potential cause, while...
متن کاملFinite Element Modelling of Impact-induced Axonal Injury in Sheep
This paper describes a numerical study of axonal injury caused by an impact to the head of the anaesthetised sheep. In the model, described in Anderson et al. (2003), injury is closely related to the peak impact force and to kinematic measurements, particularly the peak change in linear and angular velocity. A three-dimensional finite element model of the sheep skull and brain was constructed t...

متن کاملFinite-Element Modelling of Biotransistors
Current research efforts in biosensor design attempt to integrate biochemical assays with semiconductor substrates and microfluidic assemblies to realize fully integrated lab-on-chip devices. The DNA biotransistor (BioFET) is an example of such a device. The process of chemical modification of the FET and attachment of linker and probe molecules is a statistical process that can result in varia...
متن کاملCeramic Total Hip Liner Fracture Modeling in Abaqus using co-Simulation and Extended Finite Element Modeling
Due to concerns over particle generation in conventional metal-on-polyethylene hip bearings used in total hip arthroplasty (THA), interest in advanced low-wear bearing alternatives such as ceramic-on-ceramic (CoC) couples has reemerged. While ceramics demonstrate excellent compressive strength, the brittle nature of the material reduces tensile strength, possibly leading to catastrophic fractur...
