CLEAN_SmallRingTensileTest_StainlessSteel316L_ExtensionRate2_6667mmMin

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.

本数据集为测试集的一部分，包含数字图像相关（Digital Image Correlation）图像与CSV格式数据，记录了开放大学开展的SS316L不锈钢小环拉伸多位移速率试验。未处理图像格式为.NEF，文件名以‘RAW’为前缀；已处理图像格式为.TIF，文件名以‘CLEAN’为前缀。前缀之后的字符用于标识试验类型（小环试验或单轴试验），随后为材料标识，最后部分则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，其余命名规则依此类推。‘RAW’文件夹中同时包含未处理的CSV格式文件；‘CLEAN’文件夹则存储了相机采集参数（拍摄间隔、ISO感光度等）以及经过降噪处理的CSV格式实验数据。本次CSV文件的降噪处理采用巴特沃斯（Butterworth）滤波器完成。
