Abstract: 通过不同温度下(243 K、263 K、296 K、333 K、353 K和383 K)的单向拉伸试验,研究了温度对玻璃态和玻璃化转变区的丙烯腈-丁二烯-苯乙烯三元共聚物(ABS)力学性能的影响。结果表明:在低于玻璃化转变温度(383 K)的范围内,屈服强度和极限拉伸强度随温度的升高呈线性下降;杨氏模量随温度的上升呈非线性下降。本文结合双层黏塑性本构模型,利用sim-flow优化工具获取本构模型在不同温度下的材料参数,建立了温相关双层黏塑性本构模型,该本构模型可以很好地预测ABS在243~383 K范围内的应力-应变曲线。 An experimental study of temperature-dependent mechanical behavior of acrylonitrile butadiene styrene (ABS) was performed at a range of temperatures (243 K, 263 K, 296 K, 333 K, 353 K, 383 K) under uniaxial tension condition. In this temperature range, ABS was in the glass state and glass transition region. The results show that the yield stress and ultimate tensile stress decrease linearly but Young's modulus decreases nonlinearly with the increase of temperature. The material parameters of the model at different temperature were obtained by using a sim-flow optimization tool. The temperature-dependent two-layer viscoplasticity constitutive model was established. This constitutive model can predict the stress-strain curve of ABS well at different temperatures between 243 K and 383 K. 国家自然科学基金(11472165)

Abstract: 铝箔已被广泛应用于电子工业,现又被用作锂电池正极集流体,因而对于铝箔的力学性能要求也在不断提高。通过表征和研究铝箔的力学性能(弹性模量、屈服强度、断裂强度等),能够为铝箔相关技术的可靠性研究提供必要的数据支持和理论指导,从而使铝箔得到合理和可靠的使用。本文运用微拉伸、纳米压痕和动态力学分析(DMA)实验,分别研究了不同厚度的H18态和O态铝箔的力学性能。结果表明两者的弹性模量均约为30GPa,仅为块材的一半;H18态铝箔材料的断裂强度要明显强于块材,而O态铝箔材料的断裂强度则明显小于块材;此外,H18态铝箔材料的屈服强度明显大于块材,O态铝箔材料的屈服强度与块材相仿。并且,随着厚度的增加,H18态铝箔材料的延伸率显著增大,但是仍远小于块材。通过扫描电子显微镜(SEM)对铝箔材料断裂形貌进行微观分析,发现铝箔的拉伸断裂方式为脆性断裂。
Currently, aluminum foil has been widely applied in electronic industry and in lithium battery as positive electrode current collector, therefore, the requirement for aluminum foil mechanical properties is continually increased. Necessary data support and theoretical guidance can be provided for reliability study related with aluminum foil technology through understanding and characterizing aluminum foil basic mechanical properties such as elastic modulus, yield strength, and fracture strength etc, so that the aluminum foil can be used reasonably and reliably. In this paper, mechanical properties of H18-state and O-state aluminum foils with different thicknesses were experimentally studied by using micro tension, nanoindentation and dynamic mechanics analysis (DMA). Results show that elastic modulus of both H18-state and O-state aluminum foils is approximately 30 GPa, which is only half of the bulk material. Fracture strength of H18-state aluminum foil is significantly stronger than the bulk material, while O-state aluminum foil is significantly smaller than bulk material. In addition, yield strength of H18-state aluminum foils is obviously stronger than that of bulk material, while O-state aluminum foils is similar with the bulk material. With the increase of thickness, elongation of H18-state aluminum foil increases obviously, but still far less than the bulk material. Fracture morphology microscopic analysis of aluminum foil by using scanning electron microscope (SEM) finds that aluminum foil tensile fracture mode is a kind of brittle fracture
