Viscoelastic Response of HDPE 4710 Rings: Diametral Load Relaxation Dataset

This dataset includes measurements from diametral load relaxation tests conducted on HDPE 4710 pipe rings. Technicians imposed a controlled vertical deflection on each ring and recorded the reaction load over time using a calibrated load cell at 500 Hz. The file TestingConditions.csv lists the test ID, geometric properties of each ring, displacement ramp duration, and room temperature. Six files (RDXXLoadDeflect.csv) report the time series of imposed vertical deflection and reaction load for individual tests. Deflection values correspond to the vertical displacement measured at the midpoint of the ring height (i.e., half-ring deflection). The dataset also provides two supporting documents: ExperimentalSetup.txt, which describes the test configuration and procedures, and Dataset_Description.txt, which explains the file structure and variable definitions. All quantities appear in SI units. Users may multiply deflection values by two to estimate the total vertical deformation across the ring height.本数据集包含针对高密度聚乙烯（High-Density Polyethylene，HDPE）4710管环开展的径向载荷松弛试验测量数据。试验人员对每个管环施加可控的垂直挠度，并通过经校准的测力传感器以500 Hz的采样频率实时记录反作用力载荷随时间的变化。 TestingConditions.csv文件中记录了各试验的试验编号、管环的几何特性、位移斜坡加载时长以及环境室温。共包含6个命名格式为RDXXLoadDeflect.csv的文件，分别记录了各单次试验的施加垂直挠度与反作用力载荷的时间序列数据。此处记录的挠度值对应管环高度中点处测得的垂直位移，即半环挠度。 本数据集还附带两份辅助文档：ExperimentalSetup.txt详细阐述了试验配置与操作流程，Dataset_Description.txt则对文件结构与变量定义进行了说明。 所有物理量均采用国际单位制（SI）。若需估算管环高度方向的总垂直变形量，可将记录的挠度值乘以2。
