Application of Signal Analysis to Internal Friction Measurements
A fully automatized internal friction (IF) measuring system was constructed. It measures IF by proceeding a waveform analysis of the free decay vibration. The choosen method eliminates disturbances due to parasitic motions of specimen and shows a weak dispersion even at low strain amplitudes. It allows to measure short free decay keeping the specimen vibrating in quasi stationnary conditions. T...
متن کاملEffect of interstitial impurities on internal friction measurements in niobium
Measurements of internal friction as a function of temperature were carried out in samples of niobium containing different amounts of interstitial solutes (oxygen and nitrogen) and one sample of niobium containing initially only nitrogen as interstitial solute. The experimental spectra of internal friction as a function of temperature were obtained with a torsion pendulum of the inverted Kê-typ...
متن کاملSensor Measurements For Diagnostic Equipment
Piezoelectric sensors are widely used in accelerometers, for detecting failures in structures, and for vibration suppression systems among others. Such sensors can be manufactured in many different sizes, and packages to work in a variety of environments. The main characteristic of the piezoelectric material that allows for this effect is the conversion of mechanical to electrical energy. That ...

متن کاملAltering internal surface of putty impression material for better recording of tooth preparation margins
This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...
