The presented study focuses on measuring volume changes in elastomeric materials using digital image correlation (DIC), specifically the 2D DIC universal system and video-extensometer directly implemented to testing machine. Optical measurement methods were applied two-dimensional (2D) configurations during mechanical of dumbbell-shaped test specimens under uniaxial tension. measured data used ...

Flowable fill is a self-leveling and self-compacting material that is rapidly gaining acceptance and application in construction, particularly in transportation and utility earthworks. When mixed with concrete sand, standard flowable fill produces a mass density ranging from 1.8 to 2.3 g/cm(3) (115-145 pcf). Scrap tires can be granulated to produce crumb rubber, which has a granular texture and...

Introduction.-It has been shown earlierl 2 that the synthesis of the isoprenoid, rubber, by a rubber-bearing plant, guayule (Parthenium argentatum), involves acetate as an, intermediate. Not only does the administration of acetate to this plant result in a net increase in the amount of rubber formed, but, in addition, rubber synthesized by plants supplied with doubly C"4-labeled acetate possess...

The main focus of this review is on soft composites, relatively new to the literature. ballistic fabrics, mechanism energy absorption and parameters affect performance fabrics are reviewed. Adding shear thickening fluid (STF) natural rubber (NR) fabric their potential enhance impact woven considered. Shear mechanism, influence response fabric/STF composite explored. Numerical modelling techniqu...

A better understanding of elastomers’ behavior during Rapid Gas Decompression (RGD) requires advanced knowledge what is happening gas sorption and desorption. This will offer to improve numerical simulation phenomena consider a real environmental use an O-ring, as for thermal applications. previous experimental study developed testing protocols investigate the performance elastomeric O-rings. T...

Humans have been shown to be good at using active touch to perceive subtle differences in compliance. They tend to use highly stereotypical exploratory strategies, such as applying normal force to a surface. We developed similar exploratory and perceptual algorithms for a mechatronic robotic system (Barrett arm/hand system) equipped with liquid-filled, biomimetic tactile sensors (BioTac(®) from...

In the paper, influence of modified Angren kaolin on properties composite elastomeric materials based butadiene-styrene rubber has been established that addition into mixtures instead gas pedals, activators and mineral fillers causes intensive connection sulfur with macromolecules. Adsorbed surface particles its uniform distribution in composition formation structure equal force were determined...
