Experimental data set from a GFRP experimental benchmark case for validating the simulation of mode I fatigue-driven delamination in composite laminates

This data repository provides the raw and processed data to reproduce the experimental fatigue test results presented in the article entitled "Benchmark test for mode I fatigue-driven delamination in GFRP composite laminates: Experimental results and simulation with the inter-laminar damage model implemented in SAMCEF" by the same authors. In this work, experimental results from a demonstrator specimen made of a non-crimp fabric laminated Glass Fiber Reinforced Polymer (GFRP) used in the wind energy industry are provided. The selected benchmark case shows varying crack growth rates and crack front shape over the fatigue life, making it more representative of structures in service than coupon specimens. The test configuration, the methodology and the data processing are addressed in the related article. Data from Figure 7 is provided here. Five coupon specimens were tested to obtain the mode I inter-laminar fatigue crack growth rate curves. The Matlab scripts for data treatment are also included. In addition, data from Appendix B is provided. Three demonstrator specimens were tested to provide crack front geometries during the fatigue testing. In addition, a complete set of elastic, fracture and fatigue properties for the material are provided in the article. This data set, in conjunction with the associated article, constitutes a comprehensive benchmark test against which existing or future delamination growth models can be evaluated.本数据集仓库提供原始与经处理的数据，用于复现由同一作者团队撰写的题为《玻璃纤维增强聚合物复合层板I型疲劳驱动分层基准试验：基于SAMCEF内置层间损伤模型的试验结果与仿真分析》的论文中展示的疲劳试验结果。本数据集提供了风电行业中使用的无卷曲织物（non-crimp fabric）层合玻璃纤维增强聚合物（Glass Fiber Reinforced Polymer, GFRP）示范试样的试验结果。所选取的基准工况在疲劳寿命周期内呈现出变化的裂纹扩展速率与裂纹前沿形貌，相较于标准试样，更贴合实际服役结构的真实工况。相关论文详细阐述了试验配置、研究方法与数据处理流程。本仓库包含图7的相关数据：共开展5组标准试样试验，以获取I型（mode I）层间疲劳裂纹扩展速率曲线；同时附带用于数据处理的Matlab脚本。此外，还提供附录B的相关数据：共开展3组示范试样试验，以获取疲劳试验过程中的裂纹前沿几何形态。相关论文中还提供了该材料完整的弹性、断裂与疲劳性能参数。本数据集结合配套发表的论文，可构成一套完整的基准测试集，用于评估现有或未来开发的分层扩展模型。
