Compression Compression fatigue tests on single stiffener aerospace structures

This dataset contains health monitoring data collected during compression compression fatigue tests of single stiffener (Level 1) aerospace composite panels.
The coupons were initially damaged either by a low velocity impact or by an artificial disbond, located between the stiffener and the skin (a pdf file highlights the locations).
Five coupons were tested until failure and five folder contains Acoustic Emission, Lamb waves and optical fibres (Distributed sensing and FBGs) data.

This dataset is the first series of the 4 testing campaigns.

本数据集包含单加强筋（一级，Level 1）航空复合材料板在压缩疲劳试验过程中采集的健康监测数据。试验试样的初始损伤源自两类诱因：低速冲击，或是加强筋与蒙皮之间的人工脱粘（一份PDF文件标注了具体损伤位置）。其中5块试样被测试至结构失效，另有5份数据文件涵盖声发射（Acoustic Emission）、兰姆波（Lamb waves）以及光纤传感（分布式传感与光纤布拉格光栅（FBGs））相关监测数据。本数据集为4项试验批次中的首个系列试验数据。
