  "description": "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.",
