摘　　要：This paper experimentally studies the tensile deformation behavior of poly- carbonate （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.This paper experimentally studies the tensile deformation behavior of poly- carbonate （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.
