Influence of boundary conditions on the residual compressive strength of impacted thin-walled GFRP channel section profiles - research data

This dataset contains experimental and numerical force–shortening data for thin-walled composite channel section profiles subjected to compression after impact (CAI). It includes measurements from a Universal Testing Machine (UTM), optical displacement data from a Digital Image Correlation (DIC) system, and corresponding Finite Element Method (FEM) simulation results for different impact energy levels and boundary conditions. The dataset is intended to support validation, comparison, and reproducibility of structural response analyses, and includes numerical input files enabling replication of the presented FEM results.

本数据集包含受冲击后压缩（CAI）作用的薄壁复合材料槽形截面型材的试验与数值力-缩短量数据，涵盖来自万能试验机（UTM）的实测数据、数字图像相关（DIC）系统采集的光学位移数据，以及针对不同冲击能量等级与边界条件的对应有限元法（FEM）仿真结果。本数据集旨在为结构响应分析的验证、对比与可复现性研究提供支撑，同时附带可复现文中所述FEM仿真结果的数值输入文件。
