Self-ligation esthetic brackets with low frictional resistance.
OBJECTIVE To test the frictional resistance forces (FRS) generated between several archwires and (1) interactive self-ligating (ISL) brackets and (2) conventionally ligated (CL) brackets. MATERIALS AND METHODS Frictional forces produced between three different archwire combinations and self-ligating (SL) brackets (ceramic and metal-slot or all-metal) and CL brackets (metal or ceramic) were ev...
متن کاملIsotropic compression of cohesive-frictional particles with rolling resistance
Cohesive-frictional and rough powders are the subject of this study. The behavior under isotropic compression is examined for different material properties involving Coulomb friction, rolling-resistance and contact-adhesion. Under isotropic compression, the density continuously increases according to Bauers exponential law, see Ref. (Bauer 1999). However, at a certain pressure/density, the beha...
متن کاملTribological Systems of Surfaces with Frictional Resistance Reduction
In this paper are assumed micro-ridges and micro-grooves on t he journal and bearing sleeve surfaces. Friction on the boundary layer of the body moving in the oil at high Reynolds numbers may be decreased due to su ch a sculpturing of the surface. The grooved scale of the shark skin is an example of such tribological systems. There size ranges of the grooves are from 200 m to 400 m. The surface...
متن کاملFrictional Resistance of Antifouling Coating Systems
An experimental study has been made to compare the frictional resistance of several ship hull coatings in the unfouled, fouled, and cleaned conditions. Hydrodynamic tests were completed in a towing tank using a flat plate test fixture towed at a Reynolds number ~ReL! range of 2.8310 6 – 5.5310 based on the plate length and towing velocity. The results indicate little difference in frictional re...
متن کاملA reduced-order model from high-dimensional frictional hysteresis.
Hysteresis in material behaviour includes both signum nonlinearities as well as high dimensionality. Available models for component-level hysteretic behaviour are empirical. Here, we derive a low-order model for rate-independent hysteresis from a high-dimensional massless frictional system. The original system, being given in terms of signs of velocities, is first solved incrementally using a l...
