RAW_SmallRingTensileTest_StainlessSteel316L_ExtensionRate1_6mmMin

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，记录了英国开放大学开展的、针对SS316L材料、不同位移速率下的小环拉伸试验相关实验数据。未处理图像（格式为.NEF）以"RAW"作为前缀，而已处理图像（格式为.TIF）则以"CLEAN"作为前缀。文件名中前缀后的字符用于标识试验类型（小环试验或单轴拉伸试验），随后标注材料信息；最后，材料标识之后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"文件夹中还包含未处理的CSV文件；"CLEAN"文件夹则存储相机参数信息（拍摄间隔、ISO感光度等）以及去噪后的实验CSV文件。所有CSV文件均通过巴特沃斯（Butterworth）滤波器完成去噪处理。
