CLEAN_SmallRingTensileTest_StainlessSteel316L_ExtensionRate0_55mmMin

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）图像与逗号分隔值（CSV）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。未处理图像采用.NEF格式，文件名前缀为"RAW"；经后处理的图像采用.TIF格式，文件名前缀为"CLEAN"。文件名后续字段依次代表试验类型（小环试验或单轴试验）、受试材料，最后部分为十字头拉伸速率。例如"Extension Rate0_3mmMin"对应的拉伸速率为0.3 mm/min，其余命名规则以此类推。"RAW"文件夹同时包含未处理的CSV文件；"CLEAN"文件夹则存储相机采集参数（拍摄间隔、ISO感光度等）与经过去噪处理的CSV实验数据。本次实验所用CSV文件均通过巴特沃斯（Butterworth）滤波器完成去噪。
