A circumferentially flanged tibial tray minimizes bone-tray shear micromotion [PDF]

open access: yes, 2005
Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening.

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

open access: yesAdvanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

THE INFLUENCE OF COMPACTION METHODS ON THE PROPERTIES OF HOLLOW CONCRETE BRICKS UTILIZING FLY ASH AND BOTTOM ASH [PDF]

open access: yes, 2011
This study focuses on the maximal use of industrial waste from burning coal, i.e. fly ash and bottom ash, in making hollow concrete bricks (HCB). Fly ash (FA) and bottom ash (BA) obtained from East Java, Indonesia, is incorporated to partly replace the ...

Air-Coupled Surface Wave Transmission Measurement Across A Partially Closed Surface-Breaking Crack In Concrete [PDF]

open access: yes, 2011
Previous researchers have demonstrated that the transmission of surface waves is effective to estimate the depth of a surface-breaking crack in solids. However, most of the results were obtained using a well-defined crack (or notch) in laboratory.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.
