Data underlying the publication: Acoustic Emission Approach for Identifying Fracture Mechanisms in Composite Bonded Joints: A Study on Varying Substrate’s Stacking Sequence

The dataset shared here contains the acoustic emission raw data of quasi-static mode I crack propagation tests in secondary composite adhesively bonded joints. Five adhesively bonded tailored composites with different stacking sequences were manufactured and tested. The specimens underwent several damage mechanisms, including cohesive failure, delamination, fibre breaking and fibre-matrix debonding.The dataset is divided into different folders, with the specimen identification described here: https://doi.org/10.1016/j.tafmec.2024.104490. Moreover, two types of files will be saved in each folder: .tradb (transient waveforms recorded during the tests) and .pridb (file that includes all the parameters recorded for each waveform).An additional folder named Load versus Displacement contains the experimental curves taken from the quasi-static mode I test.

本次共享的数据集包含二次复合胶接接头的准静态I型裂纹扩展试验声发射（Acoustic Emission）原始数据。研究团队制备并测试了五种具备不同铺层序列的定制胶接复合材料试样，该批试样在试验过程中展现出多种损伤失效模式，包括内聚失效、分层、纤维断裂以及纤维-基体脱粘。数据集按不同文件夹分类存储，试样标识详情可参见：https://doi.org/10.1016/j.tafmec.2024.104490。此外，每个文件夹内均包含两类文件：.tradb（试验过程中记录的瞬态波形文件）与.pridb（包含各条波形全部记录参数的文件）。另有一个名为“载荷-位移”的文件夹，存储了本次准静态I型裂纹扩展试验对应的实验载荷-位移曲线。
