Abstract: Statistical analyses of three probability density functions, from Normal, Rayleigh and Weibull distributions, were applied for studying steel-rebar corrosion risk/probability in inhibitor admixed steel-reinforced concrete immersed in aggressive media of 3.0% NaCl and 0.5 M H2SO4. For these, different concentrations, ranging from 0 M to 0.29 M, of K2CrO4 were admixed in two-set steel-reinforced concrete with each set partially immersed in each of the aggressive test-solutions and which were monitored using open circuit potential techniques as per ASTM C876–91 R99. Analyses of the 30-days test-response from these showed that most of the corrosion test-data distributed like the Weibull and like the Normal distributions while just a few test-datasets distributed like the Rayleigh distribution, according to the Kolmogorov-Smirnov goodness-offit statistics. All the probability distribution fittings identified, in agreements, the 0.15 M K2CrO4 admixed steel-reinforced concrete with the least

Abstract: Foam-filled fluid (FFFluid) is an innovative material technology that can be used to design anti-vibration devices. This material technology is able to dissipate energy via a number of mechanisms due to the combination of elastic and buckling properties of foams, viscosity properties of fluids and the method of packing the material. The relationship between the energy isolation mechanisms can be altered by modifying the properties of the constituent components which provides significant opportunity for tailoring the response of the isolator to meet the different demands placed upon it. While previous studies have characterized the FFFluid shock absorbers, this paper covers the characterization of the mechanical properties of FFFluid vibration isolators. The work presented here starts by studying the parameters that have an effect on the performance of an FFFluid isolator theoretically. Then, the influence of a selected number of factors on the transmissibility of an FFFluid isolator is
