Dataset of Uniaxial Load–Unload Tensile Tests for EPDM Rubber Specimens

The dataset contains experimental stress–strain measurements obtained from uniaxial load–unload tensile tests performed on rubber specimens. The experiments were conducted at room temperature under displacement-controlled loading, with maximum extension levels ranging from 4 mm to 60 mm. The data exhibit characteristic nonlinear elastic behavior and Mullins softening, making the dataset suitable for studying viscoelasticity, hyperelastic modeling, and data-driven material characterization.
