摘要

摘要: 利用一阶弯曲共振现象，开展了复合材料悬臂梁高周弯曲疲劳试验。为了取代传统的金属疲劳理论，根据复合材料疲劳损伤渐进扩展的特点，发展了新的数值方法应用于复合材料的疲劳分析。研究局部疲劳损伤模型和周期跳跃技术，开发了复合材料悬臂梁高周弯曲疲劳的半解析法Matlab疲劳损伤分析程序；另一方面，通过开发UMAT子程序，实现了疲劳损伤模型和周期跳跃技术在商业有限元软件ABAQUS中的应用。分别使用半解析法和有限元法分析复合材料悬臂梁高周弯曲疲劳的损伤累积破坏过程，预测了其高周弯曲疲劳寿命，数值预测结果与试验结果较好吻合。

Abstract: The high-cycle bending fatigue experiment of composite cantilever beam was designed by employing the first-order bending resonance phenomenon. Based on the study of the local fatigue damage model and cycle jump technique, the Matlab-based semi-analytical algorithm for high-cycle bending fatigue analysis of the composite cantilever beam was developed to substitute for traditional metal fatigue theory. On the other hand, on the basis of UMAT subroutine, the fatigue damage model and cycle jump technology were successfully applied in the commercial software ABAQUS. The semi-analytical method and the finite element method were separately employed to analyze the progressive damage accumulation and failure process for the high-cycle bending fatigue, out of which high-cycle bending fatigue life was predicted. The numerical results are in agreement with the experimental data.
