Wear Mechanism of Superhard Tetrahedral Amorphous Carbon (ta-C) Coatings for Biomedical Applications
Tetrahedral amorphous carbon (ta-C) coatings have the potential to protect biomedical implants from wear and increase their service life. In the contribution – led by KTmfk – the biotribological effectiveness of ta-C coatings on cobalt-chromium-molybdenum and titanium alloys as well as on ultrahigh molecular weight polyethylene (UHMWPE) was studied. In metal pin-on-UHMWPE disk sliding experiments […]Tetrahedral amorphous carbon (ta-C) coatings have the potential to protect biomedical implants from wear and increase their service life.

Modelling the interaction between wearable assistive devices and digital human models
Wearable assistive devices, such as exoskeletons or orthoses, are products that support or protect people by force transmission. For their design, digital human models are increasingly used, as they allow evaluation of the biomechanical effects on the human body. The main factor for efficient human assistance is the interface between the assistive device and the […]

On the influence of fatigue damage on residual strength under high strain rates of the short fiber reinforced thermoplastic PBT GF30
In the simulation of short-fiber-reinforced thermoplastics, material parameters are usually used that originate from material testing on new specimens. In order to get closer to the condition on the road, where not only new vehicles are on the road, the influence of service loads on crash safety has to be investigated. The published work of […]

Usability or Emotionality? An investigation of influencing factors
Usability and emotionality are fundamental aspects of user experience. However, creating a product design that is both usable and emotional is a challenge for product developers, particularly due to the competing goals of both aspects. In order to make a user-oriented decision between a more usable or emotional product design, product developers need a deep […]
