Failure mechanism analysis of different types of manufacture for composite stiffened panels under axial compression load

  • 摘要: 对受到边界约束的不同工艺成型复合材料加筋板进行了轴压试验和数值模拟,研究二次胶接和共固化工艺成型加筋板轴向压缩破坏机理。轴压试验中,通过应变计实时监测试验件局部屈曲,及时记录试验件初始声响载荷,通过断面观测分析结构破坏机理。基于ABAQUS软件建立有限元模型模拟结构后屈曲损伤渐进直至破坏过程。计算结果和试验结果相吻合,研究表明工艺对结构稳定性及承载能力没有显著影响,而加筋板构型影响较大。聚甲基丙烯酰亚胺(Polymethacrylimide,PMI)泡沫不影响结构失稳载荷及破坏载荷,但能延缓结构初始损伤的发生。二次胶接成型加筋板界面临近破坏才出现损伤,而共固化成型加筋板界面损伤出现较早且扩展缓慢,表现出更好的损伤阻抗特性。
