To investigate the mechanical properties of polyvinyl-alcohol (PVA)-fiber-reinforced rubber concrete, 13 groups PVA rubber/concrete specimens with volume fractions 0%, 0.5 vol%, 1.0 and 1.5 vol% particles replacement sand ratios 10%, 20%, 30% were prepared, uniaxial compression full curve test was performed. The findings indicate that bridging effect PVA, as well synergistic particles, can impr...

In this study, we demonstrate that periods of metallic gratings on elastomeric substrates can be tuned with external strain and hence are found to control the resonance condition of surface plasmon polaritons. We have excited the plasmon resonance on the elastomeric grating coated with gold and silver. The grating period is increased up to 25% by applying an external mechanical strain. The tuna...

This paper investigates the rocking behavior of rigid bodies seismically protected by means lead rubber bearings and high damping bearings, which are most popular kinds elastomeric isolators in market. The complex nonlinear force–displacement relationship displayed such devices is predicted a phenomenological model based on small set parameters having clear mechanical meaning. algebraic nature ...
