Hydrogen molecules dissolved in rubber due to high-pressure hydrogen gas exposure have been analyzed using 1H nuclear magnetic resonance (NMR) with solution and solid-state probes. To analyze the characteristics of dissolved hydrogen in rubber materials and to compare them with gaseous phase hydrogen, we measured the NMR spectra of gaseous phase hydrogen and evaluated the chemical shifts and pr...
in this article the transient heat transfer in rubber parts has been studied. this study is usefull for estimation of the minimum curing time of the rubber parts and thereby to ensure the quality of the rubber. also is the temperature distribution during the rubber curing is well know, then the curing time could accurately be estimated, which will lead to a better curing process. in this regard...
in the presented work, sulfur concrete and rubber were used for producing functionally graded materials (fgm). the physical and mechanical properties of sulfur concrete and rubber were changed continuously across the thickness. on one side, there was just rubber and, on the other, there was pure sulfur; the properties of each substance were moved to reach another. this kind of material was cons...
Weibull distribution has been used widely by many researches around the world especially in the analysis of high voltage experimental data. Unfortunately, the statistical techniques used to analyse the high voltage experimental data are not highly accurate. In view of the foregoing, this paper presents a new statistical approach to analyze the tree inception voltage of silicone rubber and epoxy...
owing to elastic and viscous characteristics embedded rubber compounds, the dissipated energy from periodic deformation is converted into heat generation and consequently, the tire may have different body temperatures for different operating conditions. in most performed investigations, just temperature distribution is considered and the mechanical behaviour of rubber parts which are highly tem...
Detecting and localizing hard lumps in soft tissues is an important medical procedure. A psychophysics experiment measured minimum indentation forces required to detect a hard ball embedded in a soft rubber model. Ball size and finger indentation speed were varied. Threshold detection forces increased with ball size and decreased with indentation speed. The shape of the finger and contact press...
T h e frict,ion behavior of rubber materials on various contact surfaces is strongly affected by the contact pressure and the relative sliding velocity. Based on a great number of experiment,^ of rubber block moving on concrete surfaces. a friction law is present,ed in this paper. It is characterized b~ a dependence on contact pressure and sliding velocity. The identification of the required pa...
