Investigation of tensile deformation behavior of PC, ABS, and PC/ABS blends from low to high strain rates

Abstract

This paper experimentally studies the tensile deformation behavior of polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), and PC/ABS blends (with the blending ratios of PC to ABS being 80:20, 60:40, 50:50, and 40:60) from low to high strain rates. Using the universal MTS-810 machine and the split Hopkinson tension bar (SHTB) testing system, the quasi-static and impact tension tests are carried out at the room temperature. The curves of the true stress and the true strain are obtained. The deformation behaviors of PC, ABS, and PC/ABS blends are characterized in detail. The linear relationship between the strain rate and the yielding stress is given.

Modeling of the Strain Rate Dependency of Polycarbonate’s Yield Stress: Evaluation of Four Constitutive Equations

“…Besides, a sharp drop is observed at temperatures above glass transition [24]. On the other hand, the yield stress increases with an increase in strain rate [25][26][27][28]. In addition, the strain rate sensitivity is more important at high strain rates [29][30][31][32].…”

Characterization of microcellular plastics for weight reduction in automotive interior parts

“…It is well known that crazing is the main plastic deformation mechanism of ABS [215][216][217]. Foamed samples were more brittle than the solid counterparts due the presence of cells in the core region, as can be observed in The simplified regression models for each morphological and tensile parameter are summarized in Table 4.3.…”

Surface modification of carbon black for the reinforcement of polycarbonate/acrylonitrile–butadiene–styrene blends

“…The product exhibited excellent performance in the cone calorimeter and limited oxygen index (LOI) test. Thus, it can be used as additive to prepare polymer nanocomposite, with thermal stability being significantly improved [33][34][35].…”
