摘要

通过试验测量了超轻X型结构芯体与金字塔点阵芯体不锈钢夹层板的剪切性能和剪切疲劳性能

并对二者的标准化疲劳极限Δτ

/τ

值进行了比较分析.结果表明:X型结构夹层板的Δτ

/τ

值不仅与钎焊结点的平台化相关

而且也与其剪切应变幅度相关.理论分析认为

在低剪切应变幅度和高载荷率的情况下

金属网在剪切和扩展工艺过程中形成的裂纹等加工缺陷是导致夹层板剪切疲劳极限降低的主要因素.

Abstract

The shear and shear fatigue behaviors of ultralightweight X-type lattice truss-cored metallic sandwich panels with designated node area for brazing are experimentally investigated. Compared with pyramidal lattice truss-cored sandwiches

the shear endurance limit of the X-type sandwich is dependent upon not only the designated node area

but also the shear strain capacity. Further theoretical analysis demonstrates that if the shear strain capacity is low and the load ratio is high

cracks and other defects formed during the shear and expansion processes of the expanded metal sheets play a leading role in decreasing the shear fatigue performance of X-type sandwich structures.
