Research data of manuscript "Universal Characteristics of Local Strain Fields for Creep Failure Prediction"

> Each experiment folder (Test_1, Test_2, Test_3, Test_4) contains raw DIC images, corresponding strain maps (in the direction of the y-axis loading), and data from the testing machine. The naming of subfolders is consistent across all experiment folders. > Images were captured at a rate of 30 frames per second. The file named "frame.000000.png", located in the "DIC_raw_images" subfolder, is the reference image, captured from the surface of the sample before the start of the experiment. The next image after the reference image corresponds to the beginning of the primary creep phase, captured at the maximum load of the initial load ramp, when the load is stabilized at a constant level. > The subfolder "DIC_strain_maps_eyy" contains strain maps in numerical format, generated from the raw DIC images. The filenames include a suffix that corresponds to the index of the related DIC image. For example, the file "frame.000000_frame.000558.txt" is the strain map produced from the image "frame.000558.png". > The "machine_data.xlsx" file in each folder contains data recorded by the testing machine. Note that the dataset includes the entire process, including the initial load ramp. The beginning of the primary creep phase can be identified by locating the index corresponding to the maximum load.
