DIC measurements of flexible floating sheet, data underlying the publication: Measuring Hydroelastic Deformation of Very Flexible Floating Structures

Structure "test_info" contains metadata decribing the test, facility, model, and the data. Measurement data is stored per time step in cell array "Frame". X and Y coordinates as well as surface elevation Z and total elevation error H_err are stored in matrices of the same size. Corresponding data points are identified by the same matrix indices. Surface elevation and error data is stored once in dimensional form and once in non-dimensional form, the latter normalized by the amplitude of the incoming waves. Normalization is indicated by expression "norm" in the file name and by variable "test_info.norm".

本数据集包含2020年2月于代尔夫特理工大学（Delft University of Technology，TU Delft）开展的规则波实验中，柔性浮动氯丁橡胶泡沫薄板的表面高程与误差数据。

本次实验共设置两种波浪工况开展研究：
1. 标称波长495 mm、标称波幅10 mm，模型长度/波长=10
2. 标称波长990 mm、标称波幅20 mm，模型长度/波长=5

数据集以Matlab .mat格式存储，适配Matlab R2020b Update 3版本。结构体"test_info"包含描述实验、设施、模型及数据的元数据。测量数据按时间步长存储于元胞数组"Frame"中。X、Y坐标、表面高程Z及总高程误差H_err均存储于尺寸一致的矩阵中，对应数据点通过相同的矩阵索引进行标识。表面高程与误差数据分别以有量纲形式和无量纲形式存储，其中无量纲形式通过入射波波幅进行归一化处理。归一化标识可通过文件名中的"norm"字样以及变量"test_info.norm"予以确认。
