Inertial impact test of a pre-notched PMMA sample, raw dataset: Raw images, raw outputs and elements for post-processing

<pre>This dataset contains the data obtained from an inertial impact test of a pre-notched PMMA sample. Both the raw data from the experiment and some post-processed data are provided. <strong>File contents:</strong> - Videos: folder that contains videos resulting from the application of the presented methodology to an inertial impact test. It contains a video of the temporally smoothed displacement fields, the resulting strain fields and the resulting strain-rate fields. - Test: folder that contains the images from the inertial impact test + the reference image used in the presented methodology. Note that the images are numbered accordingly to their corresponding sensor number !! - Static: folder that contains images taken with a static sample. Two sets are provided: - one obtained from the same mirror face permutation: this series was taken on a previous sample. A slight rigid-body translation/rotation may exist between this static set and the experimental one. - one obtained from a random mirror face permutation: this series was taken prior to the test in the exact same position - crack.vtk: mesh used for the dic procedure for the test. The file is compatible with paraview and gmsh. - Calib_#.csv: file that contains the calibrated model corresponding to the permutation #. It is organized as follows: The first column contains the zernike polynomials parameter name (eg '00','-11' etc). The following columns contain the parameters values identifed for each sensor. Hence for instance the 3rd column contains the distortion parameters for the sensor 2 (3rd column minus 1st column); Note that: - Calib_2 corresponds to the experimental set and the static set named "good permutation". - Calib_1 corresponds to the static set named "bad permutation". - Connectivity.csv: file that contains the table of connectivity for the mesh used (crack.vtk) for the test. One row corresponds to one element, it contains the element's node numbers. - Mesh_nodes.csv: file that contains the experimental mesh nodes. The first column contains the X coordinates and the second the Y ones. - U#.csv: file that contains the nodal raw displacement in the # direction (ie, after the deconvolution of the distortions). One column corresponds to a time step. -U_VTK: folder that contains the vtk files associated to the raw displacement fields obtained during the experiment. -timeline.csv: file that contains the timeline of the experiment. </pre>本数据集采集自预开缺口的聚甲基丙烯酸甲酯（PMMA, Polymethyl Methacrylate）试样的惯性冲击试验，包含试验原始数据与部分后处理数据。**文件内容：** - Videos：该文件夹存储将所提方法应用于惯性冲击试验后得到的视频文件，包含时域平滑位移场视频、应变场视频以及应变率场视频。 - Test：该文件夹包含惯性冲击试验的图像，以及所提方法中使用的参考图像。请注意，图像的编号与其对应的传感器编号一一对应。 - Static：该文件夹包含静态试样的拍摄图像，共提供两组数据集： - 一组来自相同镜面排列：该序列采集自另一块试样，该静态数据集与试验数据集之间可能存在轻微的刚体平移/旋转。 - 一组来自随机镜面排列：该序列采集自试验前的完全相同位置。 - crack.vtk：本试验所用数字图像相关（DIC）分析流程的网格文件，可兼容Paraview与Gmsh软件。 - Calib_#.csv：存储对应编号#的校准模型文件，格式说明如下：第一列为泽尼克多项式（Zernike Polynomials）的参数名称（例如'00'、'-11'等），后续各列分别为各传感器的识别参数值。例如，第三列为传感器2的畸变参数（即第三列与第一列的差值）。 注： - Calib_2 对应试验数据集与标注为“良好排列”的静态数据集。 - Calib_1 对应标注为“不良排列”的静态数据集。 - Connectivity.csv：存储本试验所用网格（crack.vtk）的单元连接表，每行对应一个单元，内容为该单元的节点编号。 - Mesh_nodes.csv：存储试验用网格的节点坐标，第一列为X坐标，第二列为Y坐标。 - U#.csv：存储#方向上的节点原始位移数据（已完成畸变反卷积处理），每一列对应一个时间步长。 - U_VTK：该文件夹存储试验过程中得到的原始位移场对应的VTK文件。 - timeline.csv：存储试验的时间线数据。
