Dataset and Supplementary Materials of The Influence of Testing Conditions on Damage Zone of Concrete in Uniaxial Compression Test

This dataset encompasses both experimental and computational simulation data from the study "The Influence of Testing Conditions on Damage Zone of Concrete in Uniaxial Compression Test: Insights from Stereo-DIC and Computational Modeling" and our conference paper "Influence of Loading Boundary Conditions on the Strain Distribution and Stress-Strain Response in the Concrete Uniaxial Compression Test."
The data were derived from a sequence of Uniaxial Compression Tests (UCTs) on concrete specimens under varied loading boundary conditions, including lubricated Teflon plates, glued platens, and T-shaped steel caps.
The processed dataset contains information obtained through Digital Image Correlation (DIC) and comparative analyses of the results. It also includes detailed spreadsheets documenting experiment procedures, raw data, and charts for each case.
The findings indicate considerable variability in the strain data field distribution. The DIC method has revealed potential experimental errors that could have been overlooked. The data from the surface of the concrete specimens could be greatly affected by the position and size of conventional strain-measuring devices.
The computational study helps isolate factors influencing the experiments and provides deeper insights into the experimental observations. The accompanying spreadsheets contain raw data, charts, and figures case by case.
