摘要
采用ABAQUS有限元软件建立复合材料加筋板模型,分析了轴压载荷下损伤抑制带对损伤扩展的抑制效果以及对承载能力的影响。分析损伤抑制带数量和其沿蒙皮的分布等设计变量对结构剩余强度的影响,并提出损伤抑制带的设计规律。
This paper studies how tear straps arrest the damage that propagated to stiffener in the composite stiffened panel under compression load by ABAQUS. And the effects on residual strength are obtained. The effects of different number of tear straps and the distribution of tear straps along the thickness on the residual strength of composite stiffened panel are discussed. And draw a conclusion that how to design the tear straps.
