介绍了波纹几何形状对破坏性能、能量吸收、失效机理和玻璃纤维方格布/环氧复合材料管失效模式的影响。对承受轴向和侧向压力的3个具有不同几何形状的复合材料管进行试验研究。同时对相同受力条件下的径向波纹复合管、圆柱型复合管、圆柱管环绕的波纹管进行试验,以了解波纹几何形状的影响。结果表明,轴向挤压中波纹几何形状会显著影响管的承载能力。然而,侧向挤压中并没有发现波纹几何形状的影响。试验中绘制了荷载-位移曲线,因此可以对各种不同几何形状的构件进行清晰的对比。研究同时发现,径向波纹可以稳定并有效地吸收能量。
The effect of corrugation geometry on failure behavior, energy absorption, failure mechanism and fiberglass gingham / epoxy composite tube failure modes was introduced. Three composite tubes with different geometries were tested for axial and lateral pressure. Meanwhile, the radial corrugated composite pipe, the cylindrical composite pipe and the cylindrical pipe surrounded by the same force were tested to understand the influence of the corrugated geometry. The results show that the corrugation geometry in axial extrusion can significantly affect the tube carrying capacity. However, lateral extrusion did not reveal the effect of the corrugated geometry. The load-displacement curve is plotted in the test so that a clear contrast can be made between the various geometries. The study also found that radial corrugations can absorb energy stably and efficiently.
