RAW_SmallRingTensileTest_StainlessSteel316L_ExtensionRate1_5mmMin

This is a part of the test dataset (Digital Image Correlation Images and CSV data) that describes the experiments done at The Open University for the Small Ring Tensile Testing of SS316L performed at various displacement rates. Unprocessed images (.NEF format) start with the prefix 'RAW' while processed images (.TIF format) start with the prefix 'CLEAN'. The following letters after that describe the test type (Small Ring Test or Uniaxial Test), followed by the material. Lastly, after the material, the crosshead extension rate is described. For instance, 'Extension Rate0_3mmMin' refers to an extension rate of 0.3 mm/min and so on. The 'RAW' folders also contain the unprocessed CSV files. The 'CLEAN' folders contain the camera information (capture interval, ISO, etc) as well as the denoised CSV experimental files. The CSV files are denoised with the help of a Butterworth filter.

本数据集为部分测试数据集（含数字图像相关（Digital Image Correlation）图像与CSV格式数据），记录了英国开放大学针对SS316L不锈钢开展的多位移速率小环拉伸试验相关实验。未处理图像（.NEF格式）文件名前缀为「RAW」，经处理后的图像（.TIF格式）文件名前缀则为「CLEAN」。文件名后续的字母段依次标识试验类型（小环试验或单轴拉伸试验）、材料类型，最后一段则标注十字头拉伸速率。例如，「Extension Rate0_3mmMin」即代表拉伸速率为0.3 mm/min，其余命名以此类推。「RAW」文件夹中同时包含未处理的CSV格式文件；「CLEAN」文件夹则存储相机参数（拍摄间隔、ISO感光度等）以及经去噪处理后的CSV格式实验数据文件。本次实验所用CSV文件均通过巴特沃斯滤波器（Butterworth filter）完成去噪处理。
