“…Despite the variation, an increasing trend can be observed with strain rate. A lot lower failure stresses can be found on Liu et al's quasi-static testing results [6]. This is probably because of premature failure of PVB specimens.…”

“…Bennison et al [11] obtained stress-strain curves of PVB at strain rate 0.07 s À1 and 0.7 s À1 . Liu et al [6] investigated PVB tensile properties at strain rates of 0.004 s À1 , 0.02 s À1 , 0.04 s À1 , and 0.08 s À1 . The above tests all found that PVB shows viscoelastic material property under low-speed tension, and the response is influenced by loading speed.…”

“…It is highly nonlinear, time-dependent, and being capable of undergoing substantial extension. The compressive behavior of http PVB under quasi-static and dynamic loadings was exclusively studied [5,6]. The stress-strain curves at strain rates from 4 Â 10 À4 s À1 to 4 Â 10 À2 s À1 for quasi-static state and at strain rates from 700 s À1 to 4500 s À1 were obtained using conventional testing machine and Split Hopkinson Pressure Bar (SHPB) technique, respectively.…”

h i g h l i g h t sLow-speed and high-speed direct tensile tests were performed on PVB material. Stress-strain curves were derived at strain rates from 0.008 s À1 to about 1360 s À1 . The strength was found to increase with strain rate; but PVB becomes less ductile. The testing results with available testing data were summarized and analyzed. a b s t r a c tPolyvinyl Butyral (PVB) has been largely used as an interlayer material for laminated glass to mitigate the hazard from shattered glass fragments, due to its excellent ductility and adhesive property with glass pane. With increasing threats from terrorist bombing and debris impact, the application of PVB laminated safety glass has been extended from quasi-static loading to impact and blast loading regimes, which has led to the requirement for a better understanding of PVB material properties at high strain rates. In this study, the mechanical properties of PVB are investigated experimentally over a wide range of strain rates. Firstly, quasi-static tensile tests is performed using conventional hydraulic machine at strain rates of 0.008-0.317 s À1 . Then high-speed tensile test is carried out using a high-speed servo-hydraulic testing machine at strain rates from 8.7 s À1 to 1360 s À1 . It is found that under quasi-static tensile loading, PVB behaves as a hyperelastic material and material property is influenced by loading rate. Under dynamic loading the response of PVB is characterized by a time-dependent nonlinear elastic behavior. The ductility of PVB reduces as strain rate increases. The testing results are consistent with available testing data on PVB material at various strain rates. Analysis is made on the testing data to form strain-rate dependent stress-strain curves of PVB under tension.

“…Liu and Sun performed several tests at different strain rates both in tension and in compression. They then fitted the data with multiple individual material laws to cover the different rates and stress regimes [10]. Recently, Zhang et al [11] also performed high rate tests on the PVB material, reaching rates beyond 1000 s…”

Determining Material Response for Polyvinyl Butyral (PVB) in Blast Loading Situations

et al. 2016

Protecting structures from the effect of blast loads requires the careful design of all building components. In this context, the mechanical properties of Polyvinyl Butyral (PVB) are of interest to designers as the membrane behaviour will affect the performance of laminated glass glazing when loaded by explosion pressure waves. This polymer behaves in a complex manner and is difficult to model over the wide range of strain rates relevant to blast analysis. In this study, data from experimental tests conducted at strain rates from 0.01 s −1 to 400 s −1 were used to develop material models accounting for the rate dependency of the material. Firstly, two models were derived assuming Prony series formulations. A reduced polynomial spring and a spring derived from the model proposed by Hoo Fatt and Ouyang were used. Two fits were produced for each of these models, one for low rate cases, up to 8 s , and one for high rate cases, from 20 s −1 . Afterwards, a single model representing all rates was produced using a finite deformation viscoelastic model. This assumed two hyperelastic springs in parallel, one of which was in series with a non-linear damper. The results were compared with the experimental results, assessing the quality of the fits in the strain range of interest for blast loading situations. This should provide designers with the information to choose between the available models depending on their design needs.

Plasticized polyvinyl butyral (PVB)-silica nanocomposite films were formed by mixing PVB ethanol solution and silica sol, which was prepared from tetraethyl orthosilicate. The nanocomposite films were colorless and transparent even though the content of silica was 70 wt%. The glass transition temperature of PVB in the silica 2.5 wt% nanocomposites was higher by about 108C than that of plasticized PVB. The PVB-silica nanocomposite films were applied as an interlayer for laminated glass. The laminated glass made with the nanocomposite films containing less than 10 wt% silica showed good penetration resistance, not only at room temperature but also at 708C. J.
