Simulated and Experimental Tensile Test Results for Hybrid Materials (CFRP-Steel)

This dataset contains about 2000 results from hybrid-specimen tensile tests (both experimental and simulated). Each specimen (identified by hyb and optionally a human-readable hyb_name) is described by a structured set of metadata covering geometry (e.g., overlap length, ply/metal/adhesive thickness, bolt diameter), joining concept (binary flags for bolt and adhesive), and process/condition information (e.g., CFRP and metal surface preparation classes, aging state, bolt torque/prestress, friction coefficients, adhesive curing temperatures).

Material properties are included for the involved constituents—CFRP (tensile strengths in 0°/90°), metal (modulus and strength), bolt (modulus and strength), and adhesive (modulus and strength)—with values coming from datasheets for experiments or serving as input parameters for simulations. Mechanical response is captured through aligned tensile-test statistics (min/max/mean) for force, strain, and stress, plus the full stress–strain curve (stress_val array) and an overall performance metric, the hybrid tensile strength (hyb_tens_strength_val, max stress). A boolean simulated indicates whether a row originates from simulation or experiment.
