Abstract Elastomeric bearings (EB) and lead-rubber (LRB) are used in bridge structures to reduce vehicle vibrations, wind loads, earthquakes. Therefore, studying their stability is crucial ensuring the of system itself. Building upon previously proposed linear partially nonlinear models, two fully models suitable for EBs LRBs this paper. The developed adequately account interaction between hori...

long-term use of orthodontic appliances and fixation ligatures creates a favorable environment for the accumulation of oral normal microflora and increases the risk of enamel demineralization and periodontal disease. the aim of this study was to compare the antimicrobial effects of zataria multiflora extract and 0.2% chlorhexidine (chx) mouthwash on experimentally contaminated orthodontic elast...

This study proposes a new theoretical model for high-velocity impact in two kinds of targets, Kevlar/elastomer and Kevlar/epoxy composites, comprehensively discusses compares these. In this analysis, with the aid hyperelasticity theory, energy absorption equations are derived based on linear nonlinear behavior constituents to assess dependence ballistic limit interaction first, second, third, f...

This paper explores the effectiveness of shape memory alloy (SMA)/rubber-based isolation systems for seismic protection of bridges against near-field earthquakes by performing a sensitivity analysis. The isolation system considered in this study consists of a laminated rubber bearing, which provides lateral flexibility while supplying high vertical load-carrying capacity and an auxiliary device...

This study aims to investigate the effects of elastomers on fiber metal laminates (FMLs) subjected low-velocity impact loads. A compounded natural rubber layer was added conventional FMLs containing glass/epoxy composite plies and Al 6061-T6 layers, measuring its effect behavior structure in indentation at energy levels 25 45 J. It found that addition an elastomeric back face increased structur...
