Design of low-cost, fully passive prosthetic knee for persons with transfemoral amputation in India
… early stance flexionextension and a differential friction damping system for late stance and swing control. For preliminary validation of the knee mechanism two field trials were carried out on five above-knee amputees in India, which showed satisfactory performance of the early stance lock and …

Seismic response of structures with Coulomb damping
The usefulness of Coulomb (friction) damping in earthquake-resistant design of structures is examined by studying the seismic response characteristics of structures with various arrangements of sliding interfaces. First, three basic arrangements are studied for their effectiveness in reducing …

Use of Permanent Magnets to Improve the Seismic Behavior of Light-Framed Structures
… magnets, incorporated in the form of passive friction dampers, to dissipate a part of input energy induced due to strong ground motions, thereby reducing the inelastic energy dissipation demand of the lateral load resisting system. The force of attraction between the permanent magnet and …

Development of the low damage self-centering Sliding Hinge Joint
… minimal damage through sliding in Asymmetric Friction Connections (AFCs). The AFC is a type of slotted bolted connection, which is installed in the bottom web and bottom flange bolt groups. Previous studies showed that under a major earthquake, the SHJ undergoes permanent losses in elastic …

Development of A New Self-centring Low-damage Bracing System for Earthquake Resistant Structures Using Resilient Slip Friction Joints (RSFJs)
… limit state) but also the passive damping, energy dissipation and self-centring characteristics to meet the resiliency requirements when shaking with large-amplitude seismic events (Design level earthquake or beyond). This study develops a new self-centring low-damage brace using …

Study of A Direct Measuring Skin Friction Gage with Rubber Compounds for Damping
A study was conducted on the measurement of skin friction, the least under-stood component of drag. Skin friction is considered the "last frontier" in drag reduction for supersonic flight, but to understand skin friction, it must be accurately measured. This study utilized the direct measuring …
