RAW_SmallRingTensileTest_StainlessSteel316L_ExtensionRate2_0mmMin

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.

本数据集为测试数据集的一部分，包含数字图像相关（Digital Image Correlation）图像与CSV数据，记录了开放大学（The Open University）针对SS316L不锈钢开展的多位移速率小环拉伸试验。未处理图像采用.NEF格式，文件名以“RAW”为前缀；已处理图像采用.TIF格式，文件名以“CLEAN”为前缀。文件名后续的字符段依次对应试验类型（小环试验或单轴试验）、受试材料，最后一段标注十字头拉伸速率。例如，“Extension Rate0_3mmMin”代表拉伸速率为0.3 mm/min，其余命名规则以此类推。“RAW”文件夹内还包含未处理的CSV文件；“CLEAN”文件夹则存储了相机参数信息（拍摄间隔、ISO感光度等）与去噪后的实验CSV文件。所有CSV文件均通过巴特沃斯滤波器（Butterworth filter）完成去噪处理。
