    Experimental data set for Effect of Variable Amplitude Block Loading on Intralaminar Crack Initiation and Propagation in Multidirectional GFRP Laminate

    No full text
    This data repository includes the necessary data to reproduce the results presented in the paper: "Effect of Variable Amplitude Block Loading on Intralaminar Crack Initiation and Propagation in Multidirectional GFRP Laminate" by the same authors. In this work, the initiation and propagation of intralaminar matrix cracks is investigated under Variabel Ampltide fatigue loading. The data acquisition is performed through a white light camera. For further details on the methodology the reader is refered to the paper. The data in this repository is not the raw image files due to size limitations. Instead, the presented data is the coordinates of the crack endpoints for every crack in each frame. With this data the reader can post-process the data in any way they see fit, and reproduce the results from the paper. The data set consists of data for 3 Constant Amplitude low load cases, 3 Constant Amplitude hig load cases, and 5 Variable Amplitude load cases. The data is stored in MATLAB .MAT files. However, the data can easily be imported into python using the "loadmat" function from scipy.io

    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
