Dataset for: Water Weakening Effects on Brazilian Splitting and Direct Tensile Behavior of Sandstone: A Macro- to Microscopic Comparative Analysis

This dataset supports the manuscript on water weakening effects on sandstone tensile behavior. It contains one Excel file with multiple worksheets named Fig.1 to Fig.18, corresponding to the figures in the paper. The data include: (1) direct tensile test results (dry/saturated), (2) Brazilian splitting test results, and (3) PFC2D simulation results.
