中文摘要:
      基于单轴拉伸试验研究炭黑N330补强丁苯橡胶（SBR）硫化胶的应力-应变行为，通过对拉伸时试样的横截面积校正来获得SBR硫化胶的真实应力，并采用BEDA模型模拟SBR硫化胶的工程应力-应变曲线和真实应力-应变曲线。结果表明：SBR硫化胶的真实应力大于工程应力，随着炭黑N330用量的增大，SBR硫化胶的真实应力与工程应力之比逐渐增大；当炭黑N330用量为40份，SBR硫化胶的真实应力为248.24 MPa，工程应力为28.24 MPa；当炭黑N330用量为10～20份，SBR硫化胶的工程应力和真实应力均出现逾渗现象；当应变为100%～600%时，SBR硫化胶的BEDA模型的工程应力-应变模拟曲线和真实应力-应变模拟曲线与相应试验曲线很好重合，真实应力-应变曲线的拟合参数大于工程应力-应变曲线。
英文摘要:
      The stress-strain behavior of styrene-butadiene rubber（SBR）vulcanizates reinforced with carbon black N330 was studies based on uniaxial tensile tests，the real stress of SBR vulcanizates was obtained by correcting the cross-sectional area of the specimens during stretching，and the BEDA model was employed to simulate the engineering stress-strain and real stress-strain curves of SBR vulcanizates.The results showed that the real stress of SBR vulcanizates was greater than the engineering stress，with the increase of carbon black N330 amount，the ratio of real stress to engineering stress gradually increased.When the carbon black N330 amount was 40 phr，the real stress of SBR vulcanizates was 248.24 MPa，and the engineering stress was 28.24 MPa.When the carbon black N330 amount ranged from 10 to 20 phr，a percolation phenomenon was observed in both the engineering stress and real stress of SBR vulcanizates.When the strain was 100%～600%，the simulated engineering stress-strain and real stress-strain curves of the BEDA model for SBR vulcanizates coincided well with the corresponding experimental curves，and the fitting parameters of the real stress-strain curve were greater than those of the engineering stress-strain curve.
