摘要/Abstract

摘要： 复合材料胶接结构损伤变形和演化行为的实时表征对其服役的安全性和可靠性评估具有重要的意义。结合数字图像相关(Digital Image Correlation,简称“DIC”)和声发射(Acoustic Emission,简称“AE”)技术,研究循环拉伸加载条件下复合材料单搭接界面的损伤变形与破坏行为。依据单向拉伸失效载荷均值,取准静态破坏载荷的70％和80％分别进行循环拉伸加载实验。通过不同阶段复合材料胶接界面的损伤变形场、应变场信息及演化过程中获取的AE信号,分析循环加载下复合材料单搭接界面损伤破坏的力学机制与实时变形和AE特征信号的对应关系。结果表明,复合材料单搭接试件损伤破坏的实时微位移场特征和AE相对能量、撞击累积数及幅度谱等反映了胶接界面微裂纹的萌生及扩展行为。随应力水平的升高,复合材料单搭接试件破坏前的循环次数呈递减趋势。

Abstract: Researches on damage deformation and evolution behavior of adhesively bonded composite joints in real-time are of great importance for structural safety and its reliability assessment in service. In this paper, we use of Digital Image Correlation (DIC) and Acoustic Emission (AE) as complementary techniques for studying interfacial damage, deformation and failure behavior of adhesive-bonded composite single-lap joints under cyclic tension. On the basis of the average tensile failure load value, cyclic tensile tests were conducted with 70% and 80% of quasi-static failure loading, respectively. According to the damage deformation field, strain field information, and AE signals originated from damage of adhesive-bonded composite single-lap joints at different stages, the relationships between the mechanical failure mechanism of composite single-lap joints and the corresponding real-time deformation and AE signals were analyzed. The results show that the real-time micro-displacement field, AE relative energy, cumulative hits and amplitude spectra obtained from damage and failure of adhesive-bonded composite single-lap joints are connected with the initiation and propagation behavior of microcracks at adhesive interfaces. As the stress levels increase, the number of loading cycles that the joints can sustain before failure decreases.

Key words: cyclic loading, composite adhesive joints, acoustic emission, digital image correlation, damage evolution
