Abstract The rapid bio-corrosion of magnesium-based alloys, the formation hydrogen gas and, consequently, premature loss biomechanical functions hinder their applications as biodegradable implant materials. corrosion becomes even accelerated, when fretting wear occurs at junctions, a result repeated disruptions magnesium (hydr)oxide layer formed on surfaces. To improve overall performance these...

From the earliest attempts to successfully design and place dental implants, immediate loading and function have been hallmarks of treatment. Abundant failures in the early developmental stages of implants were commonplace and often occurred immediately or after a short period of functional loading. In many cases, patients were left with clinical problems more severe than their original edentul...

A B S T R A C T Various analogies have recently been proposed for comparing the stress fields induced in fretting fatigue contact situations, with those of a crack and a sharp or a rounded notch, resulting in a degree of uncertainty over which model is most appropriate in a given situation. However, a simple recent approach of Atzori–Lazzarin for infinite-life fatigue design in the presence of ...

Fretting fatigue induced by combined localized cyclic contact motion and external bulk fatigue loadings may result in premature and dramatic failure of the contacting components. Depending on fretting and fatigue loading conditions, crack nucleation and possibly crack propagation can be activated. This paper proposes a procedure for estimating these two damage thresholds. The crack nucleation b...

We present an attachment for the bass guitar which allows MIDI-controlled actuated fretting. This instrument adaptation is presented as a potential method of augmenting the bass guitar for those with upper-limb disabilities. Following a survey of 48 bassists, we found that timbral and dynamic features related to the plucking hand were most important to the survey respondents. We designed an act...
